Set metric threshold for default metrics

Running Grid Control 10.2.0.4; have not had the time to go through an upgrade to 10.2.0.5 yet.
There are several metrics I am interested in setting a threshold for, specifically the Streams Replication metrics. When I click the "All Metrics" link on the cluster database's homepage I see a category called Streams Process Count as well as several metrics within that group. Right now none of those metrics have thresholds set. I have tried adding a threshold in the monitoring config (Preferences -> Rules -> Database availability and critical states) but the Streams metrics do not appear.
Am I missing something here? I feel kind of ridiculous for asking, but I can't seem to find the answer anywhere...

Not every metric in 'all metrics' is configurable with metric thresholds.
Your workaround is to write an user definied metric.

Need Advise on Setting Critical Metric Threshold for "Status"

Hi All,
I am trying top copy all metric thresholds from OEM 9i to 10G. I ran across the metric threshold for "Status" (whether the node is up or down). It is set to "Down" and, although I'd like to set it to "Up/Down", when I hit Continue it comes back with
"The format of the critical threshold is not correct.". Does anyone know what the problem is?
Thanks
Sam

you are status metrics for all targets in grid control
the notification rules for databases,hosts,listener,aplication server are enabled the send mail if the status change.

How to change default thresholds for some metrics of all targets.

Hi!
We have a lot of servers which have to work hard.
So, our OEM very often generates messages like these:
"EM Alert: Critical:dbsora90.tsb.kz - CPU Utilization is 99.95%, crossed warning (80) or critical (95) threshold."
"EM Alert: Critical:dbsora94.tsb.kz - Disk Device c8t60A9800043346C384C344A4A63516D6Ad0(ssd4) is 99.7% busy."
"EM Alert: Critical:dbsora94.tsb.kz - CPU Load (Run Queue Length averaged over 5 minutes) is 20.78, crossed warning (10) or critical (20) threshold."
I need to change default tresholds for mentioned metrics but I can't their defenition in SYSMAN.MGMT_*-tables or suitable settings in OEM GUI.
And I have no time to edit treshholds manually for each target. )

Modification of Metric Thresholds (as this is what you are referring to), should be done using the Metrics and Policy Settings link (to be found in the Target Home page).
Don't mess around with the SYSMAN tables!
Best thing to do here is to start using Monitoring Templates for this.

Alerting Metric thresholds for Notification rules

Hi Guys,
Can i edit the Response Time (msec) metric under the Listener Availability Notification rule to alert only if the response time is breaching the alerting threshold for 5 minutes,as in for 5 consecutive occurences when this metric is pooled ?
For example we can execute dbms_server_alert.set_threshold(.....
consecutive_occurrences=>5
for a metric like redo_generated_sec
Can we do this for Response Time (msec) metric under the Listener Availability Notification rule ?
I am also not seeing this metric listed under v$METRICNAME
Any ideas...
Regards,
Swanand

I am not sure if this is related, but you can added Metrics for the Service Test associated with the Beacon via the Monitoring Setting.
Example for homepage:
Select All Targets > EM Website > Metric and Policy Settings >Tests >Monitoring Settings of homepage
Then Add/edit Metric Thresholds and Collection settings accordingly.

Set blank tab for default on new tab.

How do I set it so a new tab goes to blank instead of google? I just want my blank tab back. I fixed it a couple days ago, but now it's back to going to google and I can't find the page that told me how to fix it. Thanks!

A new tab opens by default as a blank tab (about:blank).<br />
If that isn't the case then an extension has changed that behavior.

How to set alert threshold and email alerts?

Hi!
I have configured Solution manager 3.2 to monitor
our R/3 systems.
I want to be able to set the threshold for tablespace
usage and be able to send an email if the usage
of the tablespace is 80% full.
Could anybody tell how to implement it?
Thanks!

Hi Christy:
There are different approaches to configure alerts, if you are using Solution Manager; I think you can benefit if you choose SolMan and the Central System (CEN) to handle all the monitoring and email alerting.
If this is the case, you will need to install the CCMS Agents on every satellite system in order to trigger remote alerts.
Let me know what is your idea and I can follow with you with the required steps.

How to set collection schedule for metric thresholds

Greetings All,
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
Windows Server 2008 R2Please know that I am a newbie when in regards Enterprise Manager (any version).
I am trying to use EM-Database Control version that was installed when I installed Oracle.
I am trying to activate e-mail notification when tablespace(s) usage exceeds set thresholds. Specifically the locally managed tablespaces.
I found the Metric Thresholds page, and I found the “Tablespace Space Used (%)” metric. Note this is NOT the “(dictionary managed)” metric.
I do have e-mail and credential information established.
I found where you can identify a SQL script to be executed for corrective actions for the warning and critical thresholds. However I don’t want to execute any corrective action, I am just interested in the e-mail notification.
I know I could setup a SQL script that would send an e-mail but from my reading/research I believe that e-mail notification should automatically take place so long as e-mail and credential information has been established, which has been established.
My question is:
I can find now way to set a Collection Schedule. The dictionary managed tablespace metric has a collection schedule link (i.e. Every 15 Minutes), but the non-dictionary managed tablespace metric(s) has none.
Clicking the edit icon(s) provides no way of setting the collection schedule.
Where/how do I establish a Collection Schedule for this metric?
Thanks for your time,
Bob

Hi Bob,
With Grid/Cloud Control you can modify the collection frequency (interval) for the Tablespace Space Used (%) metric for locally managed tablespaces; however, you cannot do the same in DB control.
That being said, alerts from the metric are server-generated alerts, which are generated from the monitored database target. When the space used percentage exceeds the Warning or Critical threshold, assuming you have subscribed to an appropriate notification rule for email notification, you should receive an email notification in about 1 minute or so.
The following doc may help explain more about server -generated alerts:

Setting thresholds for Metrics in OEM

I want to set thresholds for metrics in OEM and everytime I do, the following error occurs.
Error occurred while editing the metric thresholds.
Communication exception occurred while saving the thresholds data to the emd.
Error
java.lang.Exception: No such metric
Does anyone have any idea why this is happening and what can I do to fix it.
Thank you

Hi.
Monitoring templates are not permanently associated with targets.
Applying a template on a target updates the target's settings but if you modify the template afterwards you need re-apply it.
Furthermore, you can apply more than one template on a target. The second apply operation will generally override settings applied in the first one.
(As a best practice I would make sure that if I use more than one template for a specific target type , the different templates will
include different metrics).
Apply operations are logged and you can check which template was applied against which target.
This is available under "past apply operations" in the templates page.
HTH,

Oem 12c metric threshold

All,
I have a question is it feasible at all to set up the warning and alert thresholds for the disk %busy to be 100% for a period of 3 hours for all servers as a default.
After this time notificaction should be sent.
Thanks,
Marcin

"for all servers" -- once you get it working on one server, create a monitoring template using that one as the source, then apply to the remaining.
As for the 100% for a period of 3 hours -
Show all metrics
Click on disk busy 3 pencils icon.
Click edit (this is KEY)
Then enter the warning/critical *and* occurrences.
So if 15 minute collection intervals you would say 12 occurrences.

How to clear alert when a null value is returned for a metric column?

Hey all,
Recently, I've encountered a problem about clearing alert when a null value is returned for a metric column. From Oracle official doc, it seems that NO_CLEAR_ON_NULL could be used for this propose. However, it doesn't.
Here is the line from doc, you can see when NO_CLEAR_ON_NULL is set as FALSE, the null value will clear alert, and the default value for NO_CLEAR_ON_NULL is FALSE.
NO_CLEAR_ON_NULL: This attribute is used to control severity clearing when a null value is returned for a metric column. It defaults to FALSE with the behavior that a null value ends up clearing previous alert severities. With a TRUE value for this attribute, null values will be skipped in severity evaluations without clearing the severity.
TRUE | FALSE (default)
STATELESS_ALERTS: This attribute if set to TRUE indicates to EM that alerts on this
column will not have corresponding clears. This allows the UI to decide whether to
allow users to manually clear alerts on this column.
TRUE | FALSE (default)Here is my code for the metric,
-- meta definition
<Metric NAME="Flushing_Table_Overtime" TYPE="TABLE" HELP="NO_HELP">
    <Display>
      <Label NLSID="mmd_ip">Flushing Table Overtime</Label>
    </Display>
    <TableDescriptor>
      <ColumnDescriptor NAME="State" TYPE="STRING" IS_KEY="FALSE">
        <Display>
          <Label NLSID="mmd_rc_State">State</Label>
        </Display>
      </ColumnDescriptor>
      <ColumnDescriptor NAME="Time_Seconds" TYPE="NUMBER" IS_KEY="FALSE">
        <Display>
          <Label NLSID="mmd_fto_Time_Seconds">Flush Table consume Seconds</Label>
        </Display>
      </ColumnDescriptor>
    </TableDescriptor>
    <ExecutionDescriptor>
      <GetTable NAME="MysqlProcessAggregate"/>
      <GetView NAME="v_flushing_tables" FROM_TABLE="MysqlProcessAggregate">
        <Column NAME="State" />
        <Column NAME="Time_Seconds" />
        <Filter COLUMN_NAME="State" OPERATOR="EQ">Flushing tables</Filter>
      </GetView>
    </ExecutionDescriptor>
</Metric>
-- coll definition
<CollectionItem NAME="Flushing_Table_Overtime">
    <Schedule>
      <IntervalSchedule INTERVAL="10" TIME_UNIT="Min" />
    </Schedule>
    <MetricColl NAME="Flushing_Table_Overtime">
      <Condition COLUMN_NAME="Time_Seconds"
                 CRITICAL="30" OPERATOR="GT"
                 MESSAGE="There is a Flushing Table command has exceeded %critical_threshold% seconds."
                 MESSAGE_NLSID="msg_Flushing_Table_Overtime" />
    </MetricColl>
</CollectionItem>If this feature can not be achieved by coding XML, then is there a way to clear alert with Oracle Package? I have confirm neither sysman.em_severity.delete_current_severity nor sysman.em_severity.clear_alerts could do it.
Would anyone give me a hint?
Thanks in advance!
Best wishes,
Satine

WARNING. Do not confuse SQL*Plus with PL/SQL.

There is a variable command in SQL*Plus. It allows one to define bind variables. It is limited in the data types it supports. It does not support boolean as a bind variable type.
SQL*Plus is a CLI (Command Line Interface) client tool. It has a very limited vocabularly, allowing you to (primarily):
a) configure its local environment (e.g. size of the terminal ito number of characters per lines)
b) configure its bevahiour (e.g. spooling data to a file)
c) defining substitution and bind variables
And that's it. It is not PL/SQL. It is not SQL. It takes the PL/SQL and SQL you enter, and submit that to the Oracle server. (it does some basic parsing of the data to substitute variables and bind variables where applicable)

Metric threshold and Response Action

Hello,
I have a problem regarding the metric thresholds in Oracle 10gR2. I would like to set a response action for the "Tablespace full in percent"-metric, but until now I wasn't successful with that.
I tried the following steps (sorry, if I sometimes don't use the correct terms, but I have a non-English version of EM):
1. Logging in into Enterprise Manager as SYS
2. Adjusting the threshold value for the metric
3. Setting a Response Action for the metric
a) first I tried a PL/SQL-procedure
b) another time I tried a OS-command (batch file on Windows XP)
4. Clicking "OK"
EM shows me then the page with all metrics and their settings; a message says that my changes were applied correctly. Everything seems to be right, when looking at the metric I see my new threshold value as well as the Response Action. When reloading the page, my customized threshold setting is still there, but the Resonse Action "vanished". So, no surprise, the Action is never started when the threshold is reached.
Has anybody an idea why this is not working? Am I missing something? I hope I forgot no important information. Thanks for all replies!
Regards,
Lars

I thought I posted this earlier -- try the host metric log parser. It will search a given log file fo a given text string. Its quite simple to setup. There was an issue in 10.2.0.2 with the parameters in the wrong order but thats been corrected in 10.2.0.3. You could if desired put a fix it job in there that rotates the listener.log upon an error.

Metric Paper Size Defaults

I have two OfficeJet Pro 8500's and an OfficeJet 7000 that I purchased in the UK (two of them are less than 6 months old. I am frustrated that I cannot get the printers to default to metric paper sizes. I can create metric shortcuts, but I cannot remove the American 8.5" x 11" defaults. Every time the printer starts, it defaults to the USA size. I have spoken with HP (India) who didn't have a clue (of course after making me reload the software). I have the latest Microsoft Version 7 software, but this problem existed when on Vista too. Does anyone know how get these UK products to recognise that they are European and not American?

Paper size can be modified in print settings........
Change print settings
You can change print settings (such as paper size or type) from an application or the
printer driver. Changes made from an application take precedence over changes
made from the printer driver. However, after the application is closed, the settings
return to the defaults configured in the driver.
NOTE: To set print settings for all print jobs, make the changes in the printer
driver. For more information about the features of the Windows printer driver, see the
online help for the driver. For more information about printing from a specific
application, see the documentation that came with the application.
Change settings from an application for current jobs (Windows)
To change the settings
1. Open the document that you want to print.
2. On the File menu, click Print, and then click Setup, Properties, or Preferences.
(Specific options may vary depending on the application that you are using.)
3. Select the appropriate printing shortcut,y and then click OK, Print, or a similar
command.
Change default settings for all future jobs (Windows)
To change the settings
1. Click Start, point to Settings, and then click Printers or Printers and Faxes.
- Or -
Click Start, click Control Panel, and then double-click Printers.
NOTE: If prompted, enter your administrator password.
2. Right-click the printer icon, and then click Properties, General Tab, or Printing
Preferences.
3. Change the settings that you want, and then click OK.
Let me know if that helped or not.

Get alerted after 5 metric breaches for Response Time (msec) metric

Hi Guys,
Can i edit the Response Time (msec) metric under the Listener Availability Notification rule to alert only if the response time is breaching the alerting threshold for 5 minutes,as in for 5 consecutive occurences when this metric is pooled ?
For example we can execute dbms_server_alert.set_threshold(.....
consecutive_occurrences=>5
for a metric like redo_generated_sec
Can we do this for Response Time (msec) metric under the Listener Availability Notification rule ?
I am also not seeing this metric listed under v$METRICNAME
Any ideas...
Regards,
Swanand

I have no doubt this is it. I switched to the OID of the timeticks that the system has been up for and tried:
<CollectionItem NAME="Response">
<Schedule>
<IntervalSchedule INTERVAL="5" TIME_UNIT="Min"/>
</Schedule>
<Condition COLUMN_NAME="Status" CRITICAL="1" OPERATOR="LT"/>
</CollectionItem>
The corresponding snmpwalk retrieves:
-bash-3.00# ./snmpwalk -Os -v1 -c public 100.100.100.100 .1.3.6.1.2.1.1.3
sysUpTimeInstance = Timeticks: (26302086) 3 days, 1:03:40.86
Now I get a clock once in a while (it looks like its collecting) but then I revert to down. I assume that this structure is basically:
RetrievedValueForStatus OPERATOR CRITICAL triggers a CRITICAL alert and I could add another for WARNING
And then I'm making the assumption that "Running" is the state of CRITICAL or WARNING not being triggered?
I noticed Example 2-9 Default Collection File for Simple Server Alpha uses NO condition.
What happens if the system simply cannot be contacted, is there an assumption that the value is always available in these Conditions? For example, if I return the name of the system in the Snmp Fetchlet and SNMP cannot retrieve ANY values (because the system is down), would the CRITICAL condition be:
<Condition COLUMN_NAME="Status" CRITICAL="" OPERATOR="EQ"/>
I will keep going on trial an error
Thanks...

Metrics - Thresholds - Best Practices

All,
I installed em grid control 11g and configured the targets and notification rules. Now i am trying to set up thresholds, is there a best practice threshold values that someone can share for various metrics at weblogic level. I know this is a generic question and i can tune the thresholds for my environment/application usage. But there must be a ball-park threshold document somewhere for alert purposes.
Thanks in advance,
Prasad.

Hi Prasad,
There is no document giving recommendations on threshold values. Setting thresholds really depends on your environment. I recommend looking at performance history...looking at for instance a timeframe that had heavy load on the application/server but performance was good. Then set thresholds according to that....either adjust up or down as needed.
Thanks,
Nicole
