Errors at /var/log/plesk/panel.log after removing Health monitor

[Linulex]

I have removed the Health monitor, via the plesk installer at port 8447, not manualy or so, and now the plesk log at /var/log/plesk/panel.log and /var/log/plesk/health-alarm.log are full of these errors

Details: util_exec(.., 'proc_open') failed: file does not exist or is not executable: /usr/bin/sw-rrdtool
[2015-04-24 16:04:34] ERR [panel] Execution failed.
Command: /usr/bin/sw-rrdtool
Arguments: Array
(
[0] => -
)

There is an error every 5 minutes and the log is growing.
somehow plesk is still trying to run rrd tools, but this was deleted with the removal of the Health monitor

I have looked for cronjobs somewhere, but cant find any.
Does anyone knows where this cronjob is, or is this internal to plesk?

Hi Linulex,

the RRDtool is used as well by munin for example, or by webmin(stats). When installing the Plesk health monitor, the RRDtool package will be removed and replaced with the sw-rrdtool from Plesk. Unfotunately, removing the Plesk Health monitor doesn't include a re-installation of the RRDtool - package, in case of a previous replacement.

Could you check if RRDtool is installed on your system and still needed by another package on your server?


Possible solution could be to re-install the RRDtool - package and create symlinks to the RRDtool ( not tested, sorry ):

ln -s /usr/bin/sw-rrdcached /usr/bin/rrdcached
ln -s /usr/bin/sw-rrdtool /usr/bin/rrdtool
ln -s /usr/bin/sw-rrdupdate /usr/bin/rrdupdate​

Hi UFHH01

The rrdtool is not removed when removing health monitor nore is it replaced when installing the health monitor. I use munin and i have installed and deleted the health monitor a few times today for various tests.

however, you have given me an idea and i have created a link sw-rrdtool to rrdtool and that seems to work, the errors are gone and as far as i can see it doesn't make any new .rrd files is /usr/local/psa/var/health/data/localhost.

ln -s /usr/bin/rrdtool /usr/bin/sw-rrdtool
