Metrics to monitor Alert Log

Hi,
I am trying to make modification in metric for monitoring alertlog.
When I try to add a new line,it's asking for field "Time/Line Number",any one know what should be the value for that?
Description on that page --> "The table lists all Time/Line Number objects monitored for this metric. You can specify different threshold settings for each Time/Line Number object." doesn''t make much sense to me.
I gave a dummy value 50,but it doesn't seem to work..
Any help is highly appreciated... thanks...

For monitoring <11g database note 976982.1 may be of use to you: https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=BULLETIN&id=976982.1;
For monitoring 11g db's see note 949858.1 (Monitoring 11g Database Alert Log Errors in Enterprise Manager)
I your case you may want to consider to create a UDM, see Monitor Non Critical 11g Database Alert Log Errors Using a SQL UDM [ID 961682.1]

User Defined Metric for default ALERT log directory

On our system we have moved the alert log to a non-default location. If we use the wrong initialization file or something else goes haywire then trace files and alert logs get placed in the $ORACLE_HOME/rdbms/log directory.
I want to create a user defined metric for each machine that will look in all the $ORACLE_HOME/rdbms/log directories for each ORACLE_HOME on the server checking for any alert*.log or *.trc files. Creating an alert if it encounters any of these files.
I don't know if I should do it as a host UDM or an instance UDM. And more to the point how do I get it to see the multiple homes if the server has more than one.
Any ideas would be appreciated.
Thanks
Tim

Well I did it with a host UDM calling a local script (which will be installed on shared drives for the development/test and production systems).
The local script cats the /var/opt/oracle/oratab file eliminating lines beginning with # or $ then takes the second argument of each line and loops through all entries using a checkit procedure. The checkit procedure determines if the appropriate log directores exist for the oracle home and does a find on the diretory looking for alert*.log and *.trc. If there are any then global variables get updated with the count and directory name.
There is an if statement before exit that checks of the count of files is greater than zero and write an appropriate em_result and em_message depending on the results.
I then created the UDM in EM to call this script and check for critical/warning thresholds.

Tim

Alert Log File Monitoring of 8i and 9i Databases with EM Grid Control 10g

Is it possible to monitor alert log errors in Oracle 8i/9i Databases with EM Grid Control 10g and EM 10g agents? If yes, is it possible to get some kind of notification?
I know that in 10g Database, it is possible to use server generated alerts, but what about 8i/9i?
Regards,
Martin

Hello
i am interested in a very special feature: is it possible to get notified if alerts occur in alert logs in an 8i/9i database when using Grid control and the 10g agent on the 8i/9i systems?
Moreover, the 10g agent should be able to get Performance Data using the v$ views or direct sga access without using statspack, right?
Do you know where I can find documentation about the supported features when using Grid Control with 8i/9i databases?

User defined metrics for alert log errors

I want to create UDM for getting the full description of alert log ORA - error to be reported via E-mail. Can somebody guide me or help me withe script which can be used to create this alert. Currently, We get the only the message of that error is generated; which request us to manually check the alert to log to figure out the error.

Hi,
what metric did you use and what is the database version.
There are metrics related to alert log errors but those which have status at the end of a name return number of errors
and w/o status provide error description:
11g
Generic Incident - error message
Generic Incident Status - number of errors
10g
Generic Alert Log Error - error message
Generic Alert Log Error Status - number of errors
Did you set Generic Incident or Generic Alert Log Error? If description is not enough
you might use UDM but it would be easier for 11g since there are internal views which
have access to ADR, for 10g it will be required to build additional procedure (to open and read alert log)

Cloud Control 12c monitoring Oracle 11g Standard Edition alert.log

Hi guys.
I just installed Cloud Control 12c3 and added my cluster database, I have readed many papers, tech docs and tech discuss and now i have a huge confussion about packs, licensing and other fruits. Please help...
I have four Oracle 11g databases (differents hosts) Standard Edition, and i want monitoring and notificate alert.log errors. For example, if alert.log says "ORA-01438, blablabla" i want a email notification.
I read about packs, and says that "diagnostic pack" is needed for alert.log monitoring in Cloud Control 12c. But my version database is Standard Edition without packs, so I CAN'T MONITORING ALERT LOG!!!.
Question:
Do I really need Diagnostic Pack for monitoring alert.log with Cloud Control?
If Diagnostinc Pack is not necessary, how can i monitoring alert.log?
Thanks

I do not think you require any pack for alert.log content monitoring but you might need to check with Oracle rep. I am saying so because if you go to the "Alert log content" page and click on management pack for this page, Grid will display a message that this page does not require any pack.
Go to the Alert log content by "oracle database -> logs -> alert log contents"
then
go to SETUP -> management packs -> packs for this page
You will see the message will be displayed " this pages does not require any pack"
Can you also provide the doc where it says that this pae needs diagnostic pack?

Alert log monitoring in dbconsole 11.2.0.2.0

Is there a way to tune out certain ORA- alerts from alerting via dbconsole? At the moment we are getting all ORA-0600s and some of them we dont need waking up by!
Thanks.

Do you have metalink support? This is the doc you want to check into .. yes it is possible.
Database Alert log monitoring in 12c explained (Doc ID 1538482.1)
From this doc...
You need to get fancy with the regexp..
Setting thresholds for alert log metrics
Setting of the thresholds is a very complex and wide area and the values are depending on the requirements, the DBA experience and environments being monitored. This can be achieved by going to the Database target menu->Monitoring->Metrics and collection settings->Edit the "Generic Alert Log Error" from the 3 blue pencils icon on the right.
By default, the "Generic Alert Log Error" Warning threshold is set to "ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9]" which means:
ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9] - the string ORA-0
ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9] - folowed by none ore more zeroes
ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9] - followed by 600 or 60 (the ? operator means "there is zero or one of the preceding element")
ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9] - or it can be 7445
ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9] - or it can be anything between 4000 and 4999
ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9] - it can follow anything but a number
For setting the thresholds, a Regular expression (RegExp) as the one above needs to be used.

Operations Manager - KMS Idle Minutes Monitor Alerts - False Positives As Event ID 12290 Still Being Logged

Hi all,
I am using System Center 2012 R2 Operations Manager with the Key Management Service Management Pack at version 6.0.7234.0, and I keep receiving the following alert in Operations Manager:
"Idle Minutes Monitor Alert:
Key Management Service (KMS) inactivity exceeded threshold
Knowledge:
Summary:
The purpose of this rule is to alert system administrators to a possible KMS or network outage. This rule monitors the end-to-end operation of KMS activation. A notification event is created by KMS if no activation or renewal requests were logged by KMS
(activity event 12290) in the specified time interval. In addition to new activations, periodic renewal requests are expected to occur (default is 7 days). Whether or not this alert is serious depends on the number of machines in the KMS environment, how many
are actually connected, and the configured renewal interval.
Causes:
Any failure or incorrect configuration of the KMS service, other Windows components, firewall, hardware, network or routers can trigger the Idle Minutes Alert. This alert can also result from normal behavior, since it is possible that not enough machines
attempted to activate or renew during the specified time interval.
Resolutions:
The first step is to determine whether there really is a problem. Start with a known good KMS client and run (with elevated privileges) the script slmgr.vbs -ato . If the activation/renewal fails, it will report an error code. You can direct the client to
connect to a specific KMS machine by using the slmgr.vbs -skms option. The request event (12288) and response event (12289) in the Windows Application event log may provide additional information, including the identity of failing KMS machines. If there has
been a failure, check the following:
Software Licensing service (slsvc) is running.
Other KMS machine behavior is normal.
KMS firewall port is open (default is TCP 1688).
Attempt to connect to KMS using telnet to the KMS port(you won’t be able to do anything other than connect)
Use a network monitor (e.g. netmon) to capture and trace network problems.
There is one Idle Minutes Monitor that is used to monitor for activity. It may be desirable to adjust the time threshold, depending on expected KMS activity."
Despite what the alert says, there are activity events with ID 12290 being logged, but they are appearing under the 'Key Management Service' log instead of the general 'Application' log. I know that my clients are activating with the server without
any problems as I have run slmgr.vbs -ato with success on a number of them, and none are stating that activation is required. This issue was previously raised here:
http://social.technet.microsoft.com/Forums/systemcenter/en-US/1391acf8-f0be-4a48-9039-8d24e275f1fd/kms-idle-time-monitor-raise-wrong-alerts?forum=operationsmanagermgmtpacks, but I am running Windows Server 2008 R2 SP1 and the hotfix KB981314 comes
up as 'not applicable to this computer' so I assume it is part of SP1 now. I have also tried installing KB2692929, as that was cited as being a possible fix here:
http://social.technet.microsoft.com/Forums/systemcenter/en-US/8ec8ae5b-a310-4b0f-9a5f-e0599bceb93a/kms-managementpack?forum=operationsmanagermgmtpacks, however I am still seeing the same alerts.
Would greatly appreciate any further suggestions!
Many thanks

Hi,
I've checked for all the events that are generated by our servers, and there are periods of time where no requests are received for up to 18 hours, so that is no doubt why the alerts are appearing (we then sometimes see five requests in the same minute,
but there we go). I'll need to adjust the thresholds.
Thank you for your help, Chunky.1, I'll mark your reply as the answer, as it was very helpful in understanding the alert.
For anyone else who needs to check this, create a PowerShell script using the following content, and place your own details into the relevant sections in bold (without the brackets, of course). This will generate a csv file which will have the server
name in one column and the time that the request event was generated - you can then check the gaps between the requests. The script is quick and dirty, with no checks along the way, so feel free to embellish it as required.
Out-File "<directory to place file in>\KMS_check_results.csv"
$results = get-eventlog -ComputerName <KMS server hostname> -logname 'Key Management Service'|where{$_.message -match "<String which identifies servers instead of clients>"}
$filteredresults = @()
foreach($event in $results){
    #This splits up the message into sections, separated by commas, and places each section as an element in an array
    $event.Message -split ","|foreach{
        if($_ -match "<server domain suffix - e.g. contoso.com>"){
            $eventserver = $_
    $timegenerated = $event.TimeGenerated
    $filteredresults += New-Object PSObject -Property @{
        Server = $eventserver
        TimeGenerated = $timegenerated
$filteredresults|select-object server,timegenerated|export-csv "<directory to place file in>\KMS_check_results.csv" -NoTypeInformation

Alert log monitor help

Hello,
I am very new to shell scripting. Our DB is 10g on AIX. And i wanted to setup something that will monitor my alertlog and send me e-mail out. And i found this online. But have very little knowledge on cronjob. I can set one up. But this script dont tell what goes here. Here is the script that i found online. So if anyone could give me what goes where i would be thankfull. it does says put the check_alert.awk someplace. But is that where the cron comes in place. i mean do i schedule check_alert.awk in my cronjob ??? Just wanted to know what parts goes where and how to set this up the right way so i get e-mail alert for my alert log. a step - step process would be good. Thanks
UNIX shell script to monitor and email errors found in the alert log. Is ran as the oracle OS owner.

The referenced awk script (check_alert.awk). You can modify it as needed to add or remove things you wish to look for. The ERROR_AUDIT is a custom entry that a trigger on DB error writes in our environment.
$0 ~ /Errors in file/ {print $0}
$0 ~ /PMON: terminating instance due to error 600/ {print $0}
$0 ~ /Started recovery/{print $0}
$0 ~ /Archival required/{print $0}
$0 ~ /Instance terminated/ {print $0}
$0 ~ /Checkpoint not complete/ {print $0}
$1 ~ /ORA-/ { print $0; flag=1 }
$0 !~ /ORA-/ {if (flag==1){print $0; flag=0;print " "} }
$0 ~ /ERROR_AUDIT/ {print $0}
I simply put this script into cron to run every 5 minutes passing the SID of the DB I want to monitor.

I have a PERL script that I wrote that does exactly what you want and I'll be glad to share that with you along with the CRON entries.
The script runs opens the current alert_log and searches for key phrases and send e-mail if it finds anything. It then sleeps for 60 sec, wakes up and reads from were it left off to the bottom of the file, searching again and then sleeping. The only down side is it keeps a file handle open on the alert_log, so you have to kill this processes if you want to rename or delete the alert_log.
My email in my profile is not hidden.

Best Way to monitor standby, primary databases, including alert logs, etc.

Hi, Guys, I finally cutover the new environment to the new linux redhat and everything working great so far (the primary/standby).
Now I would like to setup monitoring scripts to monitor it automatically so I can let it run by itself.
What is the best way?
I talked to another dba friend outside of the company and he told me his shop not use any cron jobs to monitor, they use grid control.
We have no grid control. I would like to see what is the best option here? should we setup grid control?
And also for the meantime, I would appreciate any good ideas of any cronjob scripts.
Thanks

Hello;
I came up with this which I run on the Primary daily, Since its SQL you can add any extras you need.

Settinggs for Generic Alert Log Metric, OEM GC 10204

OS: AIX Grid Control Version: 10204
Agent:10204, Repository DB:10204
This is the setting on a 9208 DB I was testing for Generic Alert Log Error Metric (I had to change [ (square bracket with { curly brackets on the post).
Warning Metric: ORA-*
Critical Metric: ORA-0*(60{0-9}|1157|1562|1628|1650|1653|1654|1655|1656|4031|7445|16014|29740){^0-9}
The Warning metric (ORA-*) is set to a catch all else if not found in the critical metric. Not sure if there's an order the warning vs critical is read, but so far this has worked for our purposes.
In GC 10204, we can add an ORA- error to the 'Alert Log Filter Expresion' and this would prevent a metric from being sent out if matched, so if there's a particular ORA-0600 error we do not want to be sent out as critical, we could add it to to the filter to be ignored. In the Advance Setting GC example , we want to ignore "ORA-00600: internal error code, arguments {qerfxFetch_01}, {}, {}, {}, {}, {}, {}" , so we would added it to the filter as ".*ORA-00600:.*\{qerfxFetch{^\}}*\}.*"
My question - Instead of ignoring the error "ORA-00600: internal error code, arguments {qerfxFetch_01}, {}, {}, {}, {}, {}, {}", I want to move it to be a Warning, can anyone suggest any way of doing this? I've tried adding to the Warning metric {.*ORA-00600:.*\{qerfxFetch{^\}}*\}.*}|ORA-*, but this does not work, as the alert still comes out as a critical.
All suggestions are welcome.

Hi,
You did not mention database version. in 11g, the generic alert log metric will not work. For 10g, you can set this from metrics and policy settings page bu setting warning and critical thresholds for this metric to "ORA-*". And then create a notification rule for this metric.
For 11g, you need to check MOS note 949858.1

Alert log monitoring problem

Hi guys!
I have found good simple script for alert log monitoring BUT it doesnt shows date and time. How to format it so that i could see date and time as well in log output?
+#!/bin/sh+
+#GLOBS+
ALERT="ORA-";
LOGFILE=/path/to/my/alert_X.log
MYFILE=/home/user/test.log
+##+
+#get the errors out of the logfile.+
grep -h "$ALERT" $LOGFILE >> $MYFILE
+#count number of lines in myfile, and print.+
+VAR=`wc -l $MYFILE | awk -F" " '{print $1}'`+
+#echo $VAR+
+# if the amount of lines is greater than 0, then cat the file and send it to me. if not then echo all clear.+
+#size variable is the number of errors the last time the script ran+
+size=`wc -l test.last | awk -F" " '{print $1}'`+
echo $size
+# if the amount of lines is greater than 0, then cat the file and send it to me. if not then echo all clear+
+if [[ $VAR -gt $size ]] ; then+
cat $MYFILE | mail -vs "oralert" [email protected] ;
else
echo "All clear.."
fi;
rm test.last
mv test.log test.last
touch test.log

The alert_log is know to first put the date of the message into it, and then on the next line the ORA- error message.
So in the case you would find an ORA-error here, then what is the problem into going into the file and start looking at what time it occured.
Otherwise you would have to modify the script in such way that it will get more info than a 'grep' at the moment it finds the error, like using "grep -l" option, that simply matches the lines.
Then a while loop in the script could "walk" trough these lines and get the surrounding lines around that line number from the alert_log.
But, again, if an error pops up, you do want to go into the alert-file, looking up all given info e.g. about the object(s) involved, the users, if a tracefile was generated...etc,etc,.

Generic Alert log metric

I'm trying to figure out how to setup the generic alert log metric to run a corrective action based on a warning .
So when i try to work with the generic alert log metric .
it provides a time/line number which has an all others with a warning and a critical .
if i tried to add a new line with a % in the time/line number and warning expression it wont let me add it .
what am i doing wrong here . Obviously since this is the alert log i will not know the time or line number of when i will recieve this error unless i'm reading something wrong here.

if i tried to add a new line with a % in the time/line number and warning expression it wont let me add it . Try "%" (in quotes)

Alert log monitoring

Hi guys is there any kind of free utility or script which could send me peice of last alert log error produced by remote Oracle database?
I need something similar to OraSentry utility....
Just to say my 10g database work on Win platform.
Thank you!

Here's a script I use for our 9i databases.
# Set environment
. $HOME/.profile
# get a list of all Oracle DB's running and check their alert log for errors
# The 'end of monitoring' string is added to the end of the alert log after each run
# and only the messages after that are processed. Used so we don't double-check
# the same messages.
for SID in `ps -ef | grep pmon | grep -v grep | awk '{print $NF}' | sed 's/_/ /g' | awk '{print $3}'`
do
export ALERT_LOG=$ORACLE_BASE/admin/$SID/bdump/alert_$SID.log
export LASTLINE=`tail -1 $ALERT_LOG | cut -c1-5`
if [ "$LASTLINE" != "#####" ]; then
sed '/##### end of monitoring #####/,$ !d' $ALERT_LOG > /tmp/work.tmp
grep ORA- /tmp/work.tmp
if [ $? -eq 0 ]; then
mailx -s "Errors found in $SID alert log" [email protected] < /tmp/work.tmp
fi
sed '/##### end of monitoring #####/d' $ALERT_LOG > $ALERT_LOG.work
mv $ALERT_LOG.work $ALERT_LOG
echo "##### end of monitoring #####" >> $ALERT_LOG
fi
done
rm /tmp/work.tmp
Start off by inserting a comment at the end of the alert log. I use ##### end of monitoring #####
Next the script will check to see if that is the last line in the alert log. If it is then nothing has been written to the alert log since the last time the script was run...
If there is something, the script grabs everything after the '##### end of monitoring #####' and checks if it includes errors.
If it does it emails them to the dba. If not (ie: just informational messages) then it appends the '##### end of monitoring #####' line to the end of the alert log for the next run.

Create report to get lat 30days Metric alert & Alert log errors Grid

We would like to create a report to display last 30 day's mertric alert and alert log errros in EM Grid. How we can do it?

DBMS Direct,
But in the post How to be notified for all ORA- Errors recorded in the alert.log file
11iuser complain about that why he/she just get error number without any explain of arrised error.
In my situation I just get "distinct types of ORA- errors" without even any error code.
Perhaps I need to change something in emoms.properties or emd.properties.
By the way I select Message format -- Long Format
Sorry for my poor English

Need to find the way to get the actual error message in the alert log.

Hi,
I have configured OEM 11G and monitoring target versions are from 9i to 11g. Now my problem is i have defined the metrics for monitoring the alert log contents and OEM is sending alert if there is any error in the alert log but it is not showing the actual error message just it is showing as below.
============================
Target Name=IDMPRD
Target type=Database Instance
Host=oidmprd01.ho.abc.com
Occurred At=Dec 21, 2011 12:05:21 AM GMT+03:00
Message=1 distinct types of ORA- errors have been found in the alert log.
Metric=Generic Alert Log Error Status
Metric value=1
Severity=Warning
Acknowledged=No
Notification Rule Name=RULE_4_PROD_DATABASES
Notification Rule Owner=SYSMAN
============================
Is there any way to get the complete error details in the OEM alert itself.
Regards
DBA.

You need to look at the Alert Log error messages, not the "status" messages. See doc http://docs.oracle.com/cd/E11857_01/em.111/e16285/oracle_database.htm#autoId2
