Hello Alvaro,
Ensure that zenperfsnmp is running.
Zenperfsnmp collects these performance statistics, and if it failed, you
won't have data to graph. This ugly error message is simply telling you
that zenperfsnmp has not successfully collected any data to show you.
Your $ZENHOME/log/zenperfsnmp.log probably contains some reason why.
You can run zenperfsnmp from the command line and get some extra
information:
$ zenperfsnmp run -v 10

any Ideas ? permission problems ?
And the second one....I have read the list archive and i know that mysql
will be supported natively in the future .... I have some servers with
snmp and realize that snmp does not know about mysql But those added
with ssh can see the mysql process.
Theres any way to mix both ssh y snmp to have mysql support ? Should use
a nagios plugin ?
Thanks In advance and sorry for my poor english....:$
Saludos ! / Regards !
