getting problem with eximailqueue

[rlinux57]

When i have run below command the output shows messages on mail queue. It will not shown the numbers.
/usr/lib64/nagios/plugins/check_nrpe -H IP Adress -c check_eximailqueue
[Output]
Mailqueue WARNING - messages on queue

[slansing]

Can you attach the plugin? Have you checked it's usage to see if it even outputs what you are looking for?

[rlinux57]

I have added below text in visudo:

Defaults:nagios !requiretty
#nagios ALL= NOPASSWD:/usr/sbin/exim
%nagios ALL=(ALL) NOPASSWD: ALL
#nagios ALL=(ALL) NOPASSWD: /usr/local/nagios/libexec/
nagios ALL=(ALL) NOPASSWD: /usr/lib64/nagios/plugins/

[rlinux57]

Kindly check the below text of eximailqueue:

Have you tried passing it a warning or critical value yet? Or using the verbose flag? I unfortunately have no idea what the output from:

Code: Select all

/usr/bin/sudo /usr/sbin/exim -bpc

would be.

[rlinux57]

When ever i run this command manually or define command, the output does'nt show the number of messages :
/usr/lib64/nagios/plugins/check_nrpe -H IP ADDRESS -c check_eximailqueue

[Output]
Mailqueue WARNING - messages on queue


But when i run on host :
/usr/lib64/nagios/plugins/check_eximailqueue -w 25 -c 29
Mailqueue OK - 0 messages on queue

[slansing]

Hmm, it probably doesn't have handing built in to just give you the straight number. You would want to be defining warning and critical values anyways correct? As you will be checking it? What happens if you queue a message and run the check? Does it pick it up when using -w and -c?

[rlinux57]

Here's the output with -w and -c at nagios monitoring server.
/usr/lib64/nagios/plugins/check_nrpe -H IP ADDRESS -c check_eximailqueue -a '-w 25 -c 100'
[Output]
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

cang you share your nrpe.cfg from the client machie so we can see the command defined for check_eximailqueue

thanks

[rlinux57]

Below are the nrpe.cfg commands:
