ZBX_NOTSUPPORTED: Unsupported item key.

[naveensnayak]

I have zabbix agent version 2.4.2 and trying to monitor apache 2 on Ubuntu 14.04 I have imported al the templates and made all config changes when i try to test the script using

sudo -u zabbix zabbix_get -s localhost -k zapache[Uptime]

i get the errror ZBX_NOTSUPPORTED: Unsupported item key.

any ideas ?

Zapache retrieves "http://localhost/server-status?auto", check if it works on your host.

I have quite the same behavior with Debian Wheezy 7.0, zabbix 2.4.2, Apache 2.2.22

lamp# awk '/^Total Accesses:/ {print $3}' /tmp/output.html

lamp# /usr/local/bin/zabbix/zapache http://localhost/server-status TotalAccesses
ZBX_NOTSUPPORTED

I tried to add some debugging "echo" in the script, and the error is return by this test :

if [ "$rval" -ne 0 ]; then
        echo "ZBX_NOTSUPPORTED"
fi

In my case, $rval = 1, $value is empty

More debugging :

lamp# bash -x zapache http://localhost/server-status TotalAccesses

+ rval=0
+ value=
+ cache_seconds=60

In debug run You need to specify URL for machine readable status page, e.g "http://localhost/server-status?auto" or awk may fail. Please check contents of resulting /tmp/zapache-http___localhost_server-status.cache file.

There also may be problems with cache file permissions, please check that. I added a check for that error in latest commit couple of minutes ago.

OK, sorry, I had misread the manual and the code :

# zapache localhost TotalAccesses
36

 # zapache http://localhost/server-status?auto TotalAccesses
36

It's also always a good idea to check zabbix-agent logs. Script stderr will go there.
