[Xymon] analysis.cfg - LOG - keyword matching

[Becker Christian]

Hello out there,


yesterday i recognized that one of our servers has error messages in /var/log/messages every day.

The entries are:

Aug  8 11:08:26 mrv-online-4 kernel: [3356791.776050] EXT4-fs (dm-8): error count since last fsck: 6
Aug  8 11:08:26 mrv-online-4 kernel: [3356791.776080] EXT4-fs (dm-8): initial error at time 1468716722: ext4_journal_check_start:56
Aug  8 11:08:26 mrv-online-4 kernel: [3356791.776085] EXT4-fs (dm-8): last error at time 1468743842: ext4_put_super:798


In the analysis.cfg of the Xymon server, there is a DEFAULT section with the following content:

DEFAULT
# These are the built-in defaults.
        UP      3
        CLOCK   60
        LOAD    5.0 10.0
        DISK    * 90 95
        MEMPHYS 100 101
        MEMSWAP 80 90
        MEMACT  90 97
        FILE    /var/log/ntp SIZE>0
        FILE    %/var/(adm|log)/messages
        LOG     %/var/(adm|log)/messages WARNING IGNORE=%(smbd|STORVSC:*.WARNING\!|gdm-simple-greeter|GdmDisplay|GdmSession|GDM|packagekitd|parport) COLOR=yellow
        LOG     %/var/(adm|log)/messages %(I/O|read).error IGNORE=%(fd0|smbd|read_fd_with_timeout|Connection.reset.by.peer|error\.txt) COLOR=red
        LOG     %/var/(adm|log)/messages Remounting.filesystem.read-only COLOR=red
        LOG     %/var/(adm|log)/messages ERROR IGNORE=%(fd0|smbd|read_fd_with_timeout|Connection.reset.by.peer|error\.txt|gdm-simple-greeter|GdmDisplay|GdmSession|GDM|packagekitd|parport) COLOR=red
        LOG     %/var/(adm|log)/messages FAIL IGNORE=%(smbd|Connection.reset.by.peer|gdm-simple-greeter|GdmDisplay|GdmSession|GDM|packagekitd|parport|NT_STATUS_LOGON_FAILURE|LOGIN|STARTTLS) COLOR=red
        LOG     %/var/(adm|log)/messages CRITICAL IGNORE=%(smbd|gdm-simple-greeter|GdmDisplay|GdmSession|GDM|packagekitd|parport) COLOR=red
        LOG     %/var/(adm|log)/messages ALERT COLOR=red
        LOG     %/var/(adm|log)/messages There.are.errors.in.the.filesystem COLOR=red
        PROC    "syslog"


I was thinking, that this directive
        LOG     %/var/(adm|log)/messages ERROR IGNORE=%(fd0|smbd|read_fd_with_timeout|Connection.reset.by.peer|error\.txt|gdm-simple-greeter|GdmDisplay|GdmSession|GDM|packagekitd|parport) COLOR=red
should msgs let go to red, since the message of the affected server contains the keyword "error", even in lowercase. But the history of the msgs test for the affected server doesn't show any red status.
I do not have the statement (?-i) in the analysis.cfg as documented in the Xymon man-pages:

Note that Xymon defaults to case-insensitive pattern matching; if that is not what you want, put "(?-i)" between the "%" and the regular expression to turn this off. E.g. "%(?-i)WARNING" will match the word WARNING only when it is upper-case.

Is my thinking wrong?

Regards
Christian
