Shawn Smith updated SOLR-1855:
------------------------------
Attachment: checksolr
I've attached a first pass implementation of this script: !checksolr!. It's
basically the script we're using in our production environment to monitor Solr
health. As such, it's not completely generic, but it should be a decent start:
* bash script tested only on Linux
* dependencies on curl, xmllint, xmlstarlet (curl, libxml2, xmlstarlet packages)
* assumes url structure corresponding to the default multi-core Solr
configuration (http://<host>:<port>/solr/admin/cores,
.../solr/<core>/admin/ping, .../solr/<core>/replication?command=details)
* checks slave replication health assuming Solr 1.4 Java replication
* dynamically determines the set of Solr cores, so it's useful in a multi-core
deployment where the set of cores may change relatively often
Example usage:
{noformat}
$ ./checksolr -?
Usage:
checksolr [OPTIONS]
Options:
--help | -h
Print the brief help message and exit.
--man
Print the manual page and exit.
--host | -H HOST
Check this host instead of localhost.
--port | -P Port
Use this port instead of the default(8983) to connect.
--diff | -D Time difference between now and when solr last replicated
Use this option to set the maximum difference in seconds between the
time when the solr slave replicated and now.
--slave
Perform slave checks on the host instead of ping tests.
$ ./checksolr --host solrmaster1
Core "core0" returned "OK".
Core "core1" returned "OK".
Core "core2" returned "OK".
$ echo $?
0
$ ./checksolr --slave --host solrslave1
Core "core0" is up to date.
Core "core1" is up to date.
Core "core2" is having trouble replicating.
$ echo $?
1

> Script to monitor Solr health including replication status
> ----------------------------------------------------------
>
> Key: SOLR-1855
> URL: https://issues.apache.org/jira/browse/SOLR-1855
> Project: Solr
> Issue Type: New Feature
> Components: replication (java)
> Affects Versions: 1.4
> Reporter: Shawn Smith
> Attachments: checksolr
>
>
> It would be useful to have a simple monitor script that checks the health of
> all cores on a solr server.
> # Call the "ping" command and verify success.
> # Check for replication failures, for replication slaves.
> The script should return a non-zero exit code if any serious errors are
> discovered. This should make it easy to plug the script into a monitoring
> framework (Nagios, etc.)
