Resolved Health Monitoring showing only a blank page

[SKDamon]

After installing the Health Monitoring module/extension, it only shows a blank page, no data.
I can up/download config files, revert to default and detect hardware changes, but below those 4 buttons is just nothing.

I wasn't able to find any related error messages in panel.log. Re-Installing the module didn't help, using the restore default configuration doesn't help either, as did the detect hardware changes option.

Make sure that sw-collectd service is up and running:

# service sw-collectd status

Condition: start condition failed at Wed 2017-08-02 11:33:33 CEST; 6s ago
           ConditionPathExists=/etc/sw-collectd/collectd.conf was not met

/etc/sw-collectd/collectd.conf doesn't exist, but an empty subdirectory conf.d does.
Re-Installing with plesk installer and running the config script returns "Operation successful" but the service still won't start.
(Running config script from Health Monitor displays empty statistics )
Searching for default package files:

dpkg -L sw-collectd | grep -i conf
/usr/share/man/man5/sw-collectd.conf.5.gz
/usr/share/sw-collectd/postgresql_default.conf
/etc/sw-collectd/conf.d

Try to create this file at least

# cat /etc/sw-collectd/collectd.conf

Thanks, I googled for it but didn't find any config files.
Would you mind running dpkg -S /etc/sw-collectd/collectd.conf and ls -la /etc/sw-collectd/conf.d?
(Assuming you have access to a ubuntu/debian system). I smell missing packages...

sw-collectd is now running, but no log '/usr/local/psa/admin/logs/health-alarm.log', Health Monitor site is still empty after 15 minutes...

 

[IgorG]

Do you have some data in /opt/psa/var/health/data/localhost/ ?

 

[IgorG]

Also try to do following

1. Stop the sw-collectd service:
   
   # service sw-collectd stop
   
   
2. Execute the configuring script:
   
   # /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/scripts/setup-health-monitor.php
   Operation completed successfully
   
   
3. Start the sw-collectd service:
   
   # service sw-collectd start

 

[SKDamon]

systemctl stop psa-health-monitor-notificationd.service
systemctl stop sw-collectd.service
/usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/scripts/setup-health-monitor.php
Operation completed successfully
systemctl start sw-collectd.service
systemctl start psa-health-monitor-notificationd.service

Before that, I've checked the data directory, which was empty. I've created the folder localhost, uninstalled Health Monitor, restarted plesk services, installed it again and restarted plesk services one final time. I've also re-run the setup-health-monitor script with psa-health-monitor-notificationd.service running...

/usr/local/psa/admin/logs/health-alarm.log doesn't exist, no errors in panel.log, /opt/psa/var/health/data/ would be empty if I didn't create the localhost directory and I can't find any related messages in system logs.
At this point I think it's just the config files missing in conf.d...

 

[SKDamon]

I've exhausted my google-foo. Does anyone know the origin of /etc/sw-collectd/conf.d/ content?
I'm missing these and the main collectd.conf file was also missing, so some package must be missing.
Setup process ran several times, I reinstalled sw-collectd and psa-health-monitor several times, but nothing generates these config files.

Here is some more info:

/opt/psa/var/health/data/localhost/ does not exist after everything started up, and manually creating the directory won't magically fill it (sadly...)
Also, I don't know if it's supposed to be there, but I can't find any entry for the Health module in Home->Tools&Settings->Services. (It's a system service run for/by plesk, would make sense if it showed up there, right?)

Hi SKDamon,

I suggest to PURGE the two software packages with apt-get/aptitude on Debian/Ubuntu - based systems and re-check manually afterwards for possible leftovers. If all went fine and no previous files from these packages exist anymore on your server, you have then the choice to install the Plesk Server Health Monitor again over the Plesk Control Panel and the installation routine should install it as expected - with all depending and needed files.

 

[SKDamon]

I've previously re-installed sw-collectd (apt-get install --reinstall), this time I removed it via dpkg:

dpkg --remove --force-depends sw-collectd psa-health-monitor

Only /etc/init.d/sw-collectd remained (based on dpkg -L's output), which I deleted.
After that I installed Plesk Server Health Monitor, this time via the Web UI, which succeeded and left me with the message
All operations with products and components have been successfully completed.

So now, /opt/psa/var/health/data is still empty and the status page remains blank.
BTW Permissions for the data directory are 0744.

I'd be interested in where the config files would come from. System package, or does Plesk normally download them itself?
Meanwhile, here's detailed version info on sw-collectd and psa-health-monitor as well as the installer log (spoiler: no fatal errors)

Hi SKDamon,

let's start with:

So now, /opt/psa/var/health/data is still empty and the status page remains blank.
BTW Permissions for the data directory are 0744.

On my "Ubuntu 16.04" servers, the permissions are set to:

ls -lah /opt/psa/var/health/data
insgesamt 12K
drwxr-xr-x  3 root root 4,0K Jan 01 00:00 .
drwxr-xr-x  3 root root 4,0K Jan 01 00:00 ..
drwxr-xr-x 55 root root 4,0K Jun 21 09:58 localhost

rwxr-xr-x => 0755


Could you pls. post the outputs of:

ps aux | grep sw-collectd

service sw-collectd status

ls -lah /usr/share/sw-collectd

ls -lah /etc/sw-collectd
ls -lah /etc/sw-collectd/conf.d

... and pls. execute the commands:

/etc/init.d/sw-collectd stop
/usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/scripts/setup-health-monitor.php
/etc/init.d/sw-collectd start

Sorry, I thought r-x permissions were Number 4... It's drwxr-xr-x on my directory too.

Hi SKDamon,

as you can see with your outputs, you are still missing "/etc/sw-collectd/collectd.conf", so pls. see again @IgorG suggestion => #4

 

[SKDamon]

Hey UFHH01,
I've been on vacation for the past 3 weeks, sorry for that

When I came back from my vacation, Health Monitor showed empty graphs for CPU and Disks.
All the conf dirs are filled, the data directory is too, only sw-collectd.service wasn't running.

I've restarted sw-collectd, waited half an hour, now I have some beautiful graphs.
Thanks for the Help, Case Closed!
