Re: [monit] Monit to take action if outage is still there on its n'th instance eg 4th

[Martin Pala]

I have tested it (with monit-5.0.3), it works:


unicorn:~/svn/monit$ sudo ./monit -vIc /etc/monitrc
Runtime constants:
 Control file       = /etc/monitrc
 Log file           = syslog
 Pid file           = /var/run/monit.pid
 Debug              = True
 Log                = True
 Use syslog         = True
 Is Daemon          = True
 Use process engine = True
 Poll time          = 5 seconds with start delay 0 seconds
 Expect buffer      = 256 bytes
 Mail server(s)     = 127.0.0.1:25 with timeout 5 seconds
 Mail from          = address@hidden
 Mail subject       = monit alert --  $EVENT $SERVICE
 Mail message       = $EVENT Service $SERV..(truncated)
 Start monit httpd  = False
 Alert mail to      = address@hidden
   Alert on         = All events

The service list contains the following entries:

Remote Host Name      = myhost
 Monitoring mode      = active
 ICMP                 = if failed Echo Request count 3 with timeout 5 
seconds 4 times within 4 cycle(s) then exec '/bin/true' timeout 0 
cycle(s) else if succeeded 1 times within 1 cycle(s) then alert
 ICMP                 = if failed Echo Request count 3 with timeout 5 
seconds 1 times within 1 cycle(s) then alert else if succeeded 1 times 
within 1 cycle(s) then alert

System Name           = unicorn
 Monitoring mode      = active

-------------------------------------------------------------------------------
monit: pidfile '/var/run/monit.pid' does not exist
Starting monit daemon
'unicorn' Monit started
Monit instance changed notification is sent to address@hidden

[1st cycle]
'myhost' icmp ping failed
'myhost' failed ICMP test [Echo Request]
'myhost' icmp ping failed
'myhost' failed ICMP test [Echo Request]
ICMP failed notification is sent to address@hidden
'myhost' icmp ping failed, skipping any port connection tests

[2nd cycle]
'myhost' icmp ping failed
'myhost' failed ICMP test [Echo Request]
'myhost' icmp ping failed
'myhost' failed ICMP test [Echo Request]
'myhost' icmp ping failed, skipping any port connection tests

[3rd cycle]
'myhost' icmp ping failed
'myhost' failed ICMP test [Echo Request]
'myhost' icmp ping failed
'myhost' failed ICMP test [Echo Request]
'myhost' icmp ping failed, skipping any port connection tests

[4th cycle]
'myhost' icmp ping failed
'myhost' failed ICMP test [Echo Request]
ICMP failed notification is sent to address@hidden
'myhost' exec: /bin/true
'myhost' icmp ping failed, skipping any port connection tests



=> alert was sent on first cycle and program (and another alert) 
executed on 4th cycle


The test configuration is as follows:

--8<--
set daemon 5
set logfile syslog facility log_daemon
set mailserver 127.0.0.1
set mail-format {from: address@hidden
set alert address@hidden

check host myhost with address 10.1.2.3
   if failed icmp type echo then alert
   if failed icmp type echo for 4 cycles then exec "/bin/true"
--8<--


Can you run monit with -vI options and check output?


Thanks,
Martin
