Nagios Passive Agent Files

Post Release Notes and Amendments
---------------------------------

Have a look here for information on how to resolve common issues.

Issues With Performance Degradation Over Time
---------------------------------------------

There are currently issues with the speed of the Sqllite database used to hold check metrics.

It is recommended that you leave the value "metrics_db_purge_days=1" set as it is in the defaults.groovy file, otherwise the large build up of data
can cause excessive disk reads over time.

I am working on a better solution to this issue, and improving the performance of the database.

If you are still experiencing slow performance with NPA, and/or too much CPU usage, try removing the metrics.db file, and restarting the agent.
It will automatically be recreated as an empty database on startup.



Issue With Proxy Server Not Being Enabled Properly
--------------------------------------------------

The line in defaults.groovy to enable the proxy server needs to say:

proxy_enable="true"

Note the quotes above.  The default configuration may not have quotes around the value, but this is required for it to work correctly.


Windows Errors on 2008 Server
-----------------------------

You may receive the error below in the npa.log on windows:

ERROR [OSGatherer] runCmdWin(): Error occurred: Invalid XSL format (or) file name.

This is a windows bug caused by the wmic command being unable to find XSL files.  You can resolve the issue by running the following commands:

32-bit:

copy %SYSTEMROOT%\System32\en-US\*.xsl %SYSTEMROOT%\system32

64-bit:

copy %SYSTEMROOT%\System32\en-US\*.xsl %SYSTEMROOT%\SysWOW64\wbem


Trusted SSL Certs - Importing an SSL certificate:
--------------------------------------------------

If the JRE running NPA does not trust the root certificate authority which generated the certificate, you will receive errors in the logs like the following:

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

This can also occur if you are using a proxy, and the proxy certificate is not trusted.
To avoid this problem, export the certifcate from your browser, by going to the nagios address (or proxy address) manually.  You'll need to export as a DER X.509 (.cer) file.  There are instructions on doing this from Internet Explorer at the following link:

http://www.herongyang.com/Cryptography/Web-Browser-IE-Export-Certificates.html

Next, copy the file to the monitored host, and run a command similar to below:

keytool -import -file /root/proxy_cert.cer -alias my-proxy -keystore $JAVA_HOME/jre/security/cacerts/

Depending on the version of java you have installed, and the keystore location, you'll need to adjust the command.  The keystore which you change should be the 'cacerts' directory inside the jre/security/ directory, under the JAVA_HOME.

See the following link for more information:
