Performance counters from nginx, Varnish Cache and Elastic Search on Linux
Hi, we would like to monitor our few Linux devices with SCOM 2012 R2. The OS counters are working well, but we are running on Linux the applications nginx, Varnish Cache and Elastic Search from which we need the performance counters as well. Are there any
Management Packs available to read the data from these applications?
Thank you very much for any hint.
I'm not aware of any pre-built management packs for the applications you have listed.
While you could build your own management packs using OpsMgr's management pack authoring capabilities, if your monitoring needs are fairly straightforward, you could create some shell scripts to retrieve the information you want (for both health and/or performance),
and then use the Linux/UNIX script monitoring wizard in the OpsMgr console to create the monitors you want. Creating the monitors/rules is super-easy once you have the shell scripts.

Lightroom encountered and error when reading from it preview cache and needs to quit
A power outage caused my Lightroom 5.2 to shut down without closing. When I powered back up and opened lightroom it gives me an error "Lightroom encountered and error when reading from it preview cache and needs to quit" and then it says it will try to fix it the next time it opens. I have opened it 20 times and it is not fixing it. I removed the program completely and upgraded to 5.5 AND it is still giving me the same error. Is my catalog corrupt or something? I had it set to automatically load the most currently used catalog, so it is not allowing me to open or start a new catalog either. HELP!!!
Search the forum, this has been answered many times.

"Lightroom encountered and error when reading from its preview cache and needs to quit"
I keep receiving this error every time I open LR, "Lightroom encountered and error when reading from its preview cache and needs to quit" and the app won't open. It said LR would try and fix this error next time I opened it but the error remains. I tried uninstalled and installing the app and the error remains.
Any Ideas here? Is there another app that may be telling it where to look for the cache and it no longer there? I was using a ramdisk for a bit but ditched it. Not sure if that has something to do with it but it seems suspect.
Your thoughts?

Gokul: Open Lightroom folder> Preferences.
Edward: ok
Gokul: Rename Lightroom 5 Preferences.agprefs file as Lightroom 5 Preferences.agprefsOLD.
Edward: OK
Gokul: Please check if you can launch Lightroom without any error.
Edward: it shows me a welcome screen and is asking me to select my country
Edward: aka, register the software
Gokul: You can skip and launch it.
Edward: LR catalog not found
Gokul: Please select the catalog.
Edward: my original catalog?
Gokul: Yes.
Edward: testing integrity of catalog
Edward: loaded just fine
Gokul: Okay.
Gokul: Please check if you can re-launch it again.
Edward: yes, it worked!
Gokul: Excellent!
Gokul: Since your preferences were corrupted you were facing issue so we renamed the preferences file to reset it.
Edward: aha....ok
All of my import/export presets were intact along with develop user presets. I'm happy as a clam for my $10/month! -
LR encountered an error when reading from its preview cache and needs to quit.
I have the 30 day trial version of Lightroom. I was able to use it for one week, but the past 1.5-2 weeks, it has been locked up and giving this error message. How do I resolve the problem? And how do I reset the 30 day free trial? I would like to have time using the product, before deciding on the annual contract.
"LR encountered an error when reading from its preview cache and needs to quit. Lightroom will attempt to fix this problem the next time it launches."
Thank you.Delete the preview cache from the Lightroom folder in your Pictures folder if you used the default placement. It has the extension .lrdata.
You cannot reset the trial period. -

Use Windows Explorer to open the folder containing your catalog. The normal location is Pictures\Lightroom. Locate a folder with the extension .lrdata and delete that folder. Then you should be able to start Lightroom again, and Lightroom will begin building and new previews folder. Do not delete anything else.

I've tried renaming my catalog.lrcat file. I've copied over my most recent backup of the catalog.lrcat and that didn't work either.On Mac:
PS - to open the previews "folder" (a "package" is just a "special" folder) on Mac, ctrl-click and choose "Show package contents.." - same way you open any other special folder, like .app or .lrplugin..

Upgraded to 5.4 when opening lightroom get a message "encountered an error when reading from its preview cache and need to quite" tried this several time but get the same error message. Says Lightroom will attempt to fix the problem the next time it launches but that is not happening. How do it fix this?
Delete the preview cache using your operating system. It is a folder whose name ends with Previews.LRDATA. Do not delete the Lightroom catalog, which ends with .LRCAT

You need to delete your preview cache and have Lightroom rebuild it. Cache location can be found here.

I recently updated my HP laptop's OS from WIndows8 to WIndows8.1. When I went attempted to open Lightroom5 I got the following message:
"Lightroom encountered an error when reading from its preview cache and needs to quit. "
"Lightroom will attempt to fix the problem the next time it launches"
Every time I relaunch I get the same message. I'd like to understand what might be causing the problem so I can remedy and get back to my photo editing. Any clue as to how to fix this problem would be greatly appreciated.

i upgraded from lightroom 4 to lightroom 5 and installed it on a separate hard drive. Initially had no problems util my computer crashed due to the failure of the drive on which Lightroom 5 was installed. Since having my computer rectified, i am unable to use lightroom 5 getting the message "lightroom encountered an error when reading from its preview cache and needs to quit"
I can still use lightroom 4, however, i get the same message when i try to backup the catalog. This occurs during the optimisation phase of backup.
I suspect it is related to Lightroom 5 creating a catalog from the Lightroom 4 files and cannot now locate those files or that they have been corrupted.
Would appreciate any solutions / suggestions.You need to delete your preview cache and have Lightroom rebuild it. Cache location can be found here.

You don't delete a file, you have to delete a folder. Is that what you did?
If you deleted the folder specified above, and you still get the message, then it's the wrong folder. Use your operating system's search function and find ALL folders on ALL disks whose name ends with Previews.LRDATA, delete each one found, and then try opening Lightroom. -
I have a question about Lightroom 5... I used it last night, I go to get on it today and its will not open. I have an error msg "Lightroom encountered an error when reading from its preview cache and needs to quit" Lightroom will attempt to fix the problem when reopened
