[Geoserver-users] Monitoring Geoserver

Which is the best method to monitoring Geoserver activity in order to prevent unexpected fails or shutdowns? I am asking that because my geoserver installation sometimes come down, and ideally I would like to have an script that will check its state and restart geoserver automatically if it fails. By the way it is running under Ubuntu/Linux.

Thank you.

Hi,

There is no really way to monitor GeoServer in this manner... this is
something which probably falls into the realm of JMX or something like
that.. which is currently a feature we do not have.

However, your best bet is probably a little shell script set up in cron
which just attempts to do a request to the server with wget. Something like:

wget http://<server:port>/geoserver/welcome.do
if [ "$?" != "0" ]; then
  sh $GEOSERVER_HOME/bin/startup.sh
fi

However... that begs the question as to why your server is crashing?
Which version of GeoServer are you using? Also, if you include some
information about how you use GeoServer we may be able to help. THings
like what type of data you are serving up, etc...

I know that on our production server we had a similar issue. One thing
that helped was the recent postgis connection pooling stuff that Andrea
implemented. If you use postgis that might be something to consider.

In our geoserver setup a postgres stores is sometimes unavailable. It seems
Geoserver doesn't always regain a connection to the db-server. This results
in a clean picture which shows the error message.
On the other side our monitoring system (zabbix) needs a tcp status error
code or the availability of some textual content to confirm the request.
Since its a clean picture Geoserver returns an error check is not possible.
The WMS parameter for exception format ain't usable because of the
restrained conditions of the monitoring system. The monitoring needs a tcp
statuscode that the picture couldn't be made.
What are the settings on the geoserver to attain this?
