I have an Ubuntu server 16.04 where I've installed observium to monitor the server itself and this part is working fine, I can see the event logs.

After that I have followed instructions on how to add syslog: http://docs.observium.org/syslog/ But when I open syslog on the server there is error message:

"No syslog entries found!".

Is there anything else I need to do (aside from the Observium webpage instructions above)?

Thank you

UPDATE 1:

rsyslogd version 8.16.0

When I try to use direct logging it works fine.

So here is the configuration file:

#---------------------------------------------------------
#send remote logs to observium

template(name="observium"
         type="string"
         string="%fromhost%||%syslogfacility%||%syslogpriority%||%syslogseverity%||%syslogtag%||%$year%-%$month%-%$day% %timereported:8:25%||%msg%||%programname%\n")

$ModLoad omprog

# rsyslog Input Modules
input(type="imudp"
      port="514"
      ruleset="observium")

# rsyslog RuleSets
ruleset(name="observium") {
    action(type="omprog"
           binary="/opt/observium/syslog.php"
           template="observium")
}

*.* stop
#---------------------------------------------------------

And instead of that I put it without ruleset:

#---------------------------------------------------------
#send remote logs to observium

#ceph-mon.=notice; ~

template(name="observium"
         type="string"
         string="%fromhost%||%syslogfacility%||%syslogpriority%||%syslogseverity%||%syslogtag%||%$year%-%$month%-%$day% %timereported:8:25%||%msg%||%programname%\n")

$ModLoad omprog


action(type="omprog"
           binary="/opt/observium/syslog.php"
           template="observium")

*.* stop
#---------------------------------------------------------

It works :)

So there is another question. Do I need to use ruleset? If so, has anybody else experienced the same/similar issue and how did you solve it?

Thank you!

Yea I saw this issue too.

I mistakenly enabled "input(type="imudp" port="514")" in both rsyslogd.conf and 30-observium.conf. You want to enable the imudp module in rsyslogd.conf and enable the input->ruleset action for it in 30-observium.conf

/etc/rsyslog.conf; 

provides UDP syslog reception
module(load="imudp")
#input(type="imudp" port="514")

/etc/rsyslog.d/30-observium.conf should be;

#---------------------------------------------------------
#send remote logs to observium

template(name="observium"
     type="string"
     string="%fromhost-ip%||%syslogfacility%||%syslogpriority%||%syslogseverity%||%syslogtag%||%$year%-%$month%-%$day% %timereported:8:25%||%msg%||%programname%\n")

$ModLoad omprog

# rsyslog Input Modules
input(type="imudp"
      port="514"
      ruleset="observium")

# rsyslog RuleSets
ruleset(name="observium") {
    action(type="omprog"
           binary="/opt/observium/syslog.php"
           template="observium")
}

#& stop
#---------------------------------------------------------

I also had to comment out the last line as it was making rsyslog silently fail.

PS; Every time you make changes to the syslog filters, you need to restart rsyslog as it caches the resulting syslog.php script at startup.
