[monit] Building RPMS from monit 5.0_beta7.tar.gz

[Andres Tarallo]

Here are some quick notes after sucsesfully building RPMs on CentOS 5.2. I'm very new to building my RPM, please apologize my ignorance.

Martin Pala suggested doing rpmbuild -tb monit 5.0_beta7.tar.gz. It doesn't succedd, it outputs the following errors:

sh: monit: No such file or directory
sh: monit: No such file or directory
error: Name field must be present in package: (main package)
error: Version field must be present in package: (main package)
error: Release field must be present in package: (main package)

error: Summary field must be present in package: (main package)
error: Group field must be present in package: (main package)
error: License field must be present in package: (main package)

After copying  monit 5.0_beta7.tar.gz to /usr/src/redhat/SOURCES/ and monit.spec to /usr/src/redhat/SPECS I've did an rpmbuild -ba monit.spec. I've got an error. Editing monit.spec I delected STATUS from %doc. A new run to rpmbuild and got my RPMS

The RPMS seem to install fine.

You can run monit in verbose mode and verify what happened:

 monit -vI

The described problem could be startup synchronization bug in monit which was solved in upcoming monit-5.0.

You can get monit-5.0_beta7 here:
http://www.mmonit.com/monit/download/

To create binary RPM from source distribution it should be sufficient to download it and run:

 rpmbuild -tb monit 5.0_beta7.tar.gz

I have a bunch of Centos 5.2 Servers running Apache, I've installed monit 4.9 (RPMs from DAG repository). These servers are heavily loaded most of the day (average 1 min over 20, many hours a day). I keep getting the following messages in my Mailbox:

** Subject httpd Timeout - httpd unmonitor on XXXXX: 'httpd' service timed out and will not be checked anymore.
** Subject httpd Connection failed - httpd restart on XXXXXX: 'httpd' failed protocol test [HTTP] at INET[WW.WW.WWW.ZZZ:80] via TCP.
** httpd Does not exist - httpd restart on XXXXXX: 'httpd' process is not running.

The last one really puzzles me, because Apache is actually running !!!!!

My monit configuration file

set daemon  180
set logfile syslog facility log_daemon

set mailserver mail.company.net <http://mail.company.net>
set mail-format { from: address@hidden <mailto:address@hidden>

subject: $SERVICE $EVENT
message: $SERVICE $ACTION on $HOST: $DESCRIPTION.}
set httpd port 2812 and
    use address localhost  # only accept connection from localhost
    allow localhost        # allow localhost to connect to the server and
check system XXXXXX
   if loadavg (1min) > 50 then alert
   if loadavg (5min) > 75 then alert
   if memory usage > 90% then alert
   if cpu usage (user) > 99% then alert
   if cpu usage (system) > 99% then alert
   if cpu usage (wait) > 99% then alert

   alert address@hidden <mailto:address@hidden>

check file apache_bin with path /usr/sbin/httpd
  group apache
  if failed checksum then unmonitor
  if failed permission 755 then unmonitor
  if failed uid root then unmonitor

check process httpd with pidfile /var/run/httpd.pid
   start program = "/etc/init.d/httpd start"  as uid 0 as gid 0
   stop program  = "/etc/init.d/httpd stop" as uid 0 as gid 0
   if cpu > 99% for 5 cycles then restart
   if loadavg(5min) greater than 45 for 3 cycles then restart
   if failed host WW.WW.WWW.ZZZ port 80 protocol HTTP request "/site/page.php" timeout 15 seconds 10 cycles then restart
   if 6 restarts within 10 cycles then timeout

   alert address@hidden <mailto:address@hidden>

   depends on apache_bin
   group apache

I'm pulling my hair, It doesn't work flawlesly. I receive many alerts, even when the servers are working. Thanks
