The command-line is very long (ca. 3.5kB), but it should work - which monit version do you use? (monit -V). Monit 5.25.0 command-line limit is currently 4kB.

[Maruthirao]

Unable to get the version, $ monit -V -bash: monit: command not found

but i have installed monit-5.8.1-4.x86_64.rpm

[Tildeslash]

Please try to upgrade monit ... i think version 5.8.1 had lower command-line limit (1kB).

You can build monit RPM from the source code this way:

rpmbuild -tb monit-5.25.0.tar.gz
