I'm not sure if it's copy&paste typo, but the size test is not allowed in the "check process" context:

--8<--
check process tomcat7 with pidfile /var/run/tomcat7.pid

if size = 0 then exec "/bin/rm /var/run/tomcat7.pid" <------------------------ error

start program = "/etc/init.d/tomcat7 start" with timeout 60 seconds
...
--8<--

The "check file" test is not necessary ... the pidfile based process check will automatically trigger restart if the pidfile is missing.

That worked thank you. Now i am running into another error

For tomcat, and Mongo db. I try to check the pid file and start if pid file doesnt exist. The the config is shown below.

##

# Check Tomcat7
check process tomcat7 with pidfile /var/run/tomcat7.pid

if size = 0 then exec "/bin/rm /var/run/tomcat7.pid"
start program = "/etc/init.d/tomcat7 start" with timeout 60 seconds

stop program = "/etc/init.d/tomcat7 stop"
if failed host 127.0.0.1 port 8080 protocol http then restart

if 5 restarts within 5 cycles then timeout
group web

###

I get the error
monit: Error reading pid from file '/var/run/tomcat7.pid' ...

monit: Error reading pid from file '/var/lib/mongodb/mongod.lock'

How would go about fixing this error . I tried adding the line

check file tomcat7.pid with path /var/run/tomca7.pid if size = 0 then exec "/bin/rm /var/run/tomcat7.pid"

But it gives me syntax error that ###/etc/monit/monitrc:86: Error: syntax error 'size'

How can i fix this...

Hello,

the problem is this line (4x in your configuration file):

--8<--
if 5 restarts within 5 cycles then timeout and alert

--8<--

Only one action is possible (and alert is implicit part of timeout) => it should be changed to this:

--8<--
if 5 restarts within 5 cycles then timeout
--8<--

Martin

Hello, i am setting up monit for monitoring our servers. Please check my configuration file for monitrc. For some reason it starts failing from check filesystem rule which i have highlighted below. If i comment that whole section of for the check file system.. the error starts moving on to the next rules down................. not sure how to trouble shoot this error. This has been really frustrating. Any help is appreciated here...................
