Munin node –> Can’t exec /usr/share/munin/plugins

Just happened on couple of SLES 9 servers after installing the followings 

the server just came back with postfix plugin.

perl-Net-Server-0.87-29.4.i586.rpm
munin-node-1.2.4-1.sles9.rpm

But by default munin plugins are

cpu entropy forks if_eth0 iostat memory mysql_slowqueries  open_files processes df exim_mailqueue

if_err_eth0  if_eth1 irqstats mysql_bytes mysql_threads open_inodes

swap df_inode  exim_mailstats if_err_eth1 interrupts load mysql_queries 

netstat postfix_mailvolume vmstat

Then I manually did symbolic links from /etc/munin/plugins to /usr/share/munin/plugins

beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/cpu cpu
beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/df df
beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/df_inode df_inode
beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/load load
beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/memory memory
beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/processes processes
beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/if_eth0 if_eth0
beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/if_err_eth0 if_err_eth0
beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/if_eth1 if_eth1
beastie:/etc/munin/plugins # ln -s /usr/share/munin/plugins/if_err_eth1 if_err_eth1

Now after this the munin-node crashed and failed to show graph even for postfix.

While checking the log for munin in /var/log/munin/munin-node.log, I got the following error message

If you ever get these kinds of errors don’t forget to add plugins and permissions in /etc/munin/plugin-conf.d/munin-node file.

$cat /etc/munin/plugin-conf.d/munin-node
#
# This file contains configuration options for the plugins. Three
# options are understood by munin-node itself:
#
#       user <user>         # Set the user to run the plugin as
#       group <group>       # Set the group to run the plugin as
#       command <command>   # Run <command> instead of the plugin. %c
#                             expands to what would normally be run.
#   env.<variable>      # Sets <variable> in the plugin’s environment, see the
#                         individual plugins to find out which variables they
#                         care about.
#

You have to do this only when you get those error messages Cheers

daemontools for UNIX services

daemontools is a collection of tools for managing UNIX services.

supervise monitors a service. It starts the service and restarts the service if it dies. Setting up a new service is easy: all supervise needs is a directory with a run script that runs the service.

multilog saves error messages to one or more logs. It optionally timestamps each line and, for each log, includes or excludes lines matching specified patterns. It automatically rotates logs to limit the amount of disk space used. If the disk fills up, it pauses and tries again, without losing any data.

Linux rlimit problem

On Linux, we have started experiencing the following problem:

Jun 11 14:07:52 10.1.123.234 kernel: open files rlimit 1024 reached for uid 0 pid 7127 (seen 2 times)

The following seems to fix the problem after a reboot:

Modify /etc/init.d/cron and add the line in red.

case “$1″ in
    start)
ulimit -n 65536
        echo -n “Starting CRON daemon”
        ## Start daemon with star

Create /etc/initscript with the following:

# Increase the hard filedescriptor limit for all processes
# to 65536.  The soft limit is still 1024, but any unpriviliged
# process can increase it’s soft limit up to the hardlimit
# with “ulimit -Sn xxx” (needs a 2.2.13 or later Linux kernel).
ulimit -Hn 65536

# Execute the program.

    a.  mkdir /mnt/root
    b.  mount /dev/sda1 /mnt/root/boot

5.  Manually mount your LVM stuff:
    b.  vgscan
    c.  vgchange -a -y rootvg
    d.  mount /dev/rootvg/lvroot /mnt/root/boot
    d.  mount /dev/rootvg/lvusr /mnt/root/boot/usr
    d.  mount /dev/rootvg/lvopt /mnt/root/boot/opt
    d.  mount /dev/rootvg/lvhome /mnt/root/boot/home
    d.  mount /dev/rootvg/lvvar /mnt/root/boot/var

** You can now update your configuration to recover your system from what 
   ever you did to get to this point..
