[Xymon] File monitor not working in Xymon - using file list generated by wildcard

[Don Kuhlman]

Thanks Cynthia, Larry, and Ryan!

I modified the client-local.cfg file as below:
[MYSQLSERVER01]
file:`find /Volumes/MySQL_Backups/ -name "*.sql" -mtime 0  2>/dev/null | sort -r |head -1 --lines=1`

The webpage shows the file is present -
 Fri Oct 5 08:35:16 CDT 2012 - Files ok

[green] /Volumes/MySQL_Backups/mysql_backup_20121005.sql<http://srmxymon.ambrosi.com/xymon-cgi/svcstatus.sh?CLIENT=MYSQLSERVER01&SECTION=file:/Volumes/MySQL_Backups/mysql_backup_20121005.sql>

If I click the link on the webpage it gives this:
[file:/Volumes/MySQL_Backups/mysql_backup_20121005.sql]

type:100000 (file)
mode:644 (-rw-r--r--)
linkcount:1
owner:0 (root)
group:0 (root)
size:501060
clock:1349444303 (2012/10/05-08:38:23)
atime:1349425844 (2012/10/05-03:30:44)
ctime:1349413801 (2012/10/05-00:10:01)
mtime:1349413801 (2012/10/05-00:10:01)

Next I changed the directory so no file matches the find command and then the files icon goes white and gives me the "No files checked" message.

Fri Oct 5 08:45:23 CDT 2012 - Files ok

No files checked




Can anyone advise how I translate that into an email to our DBA to indicate the file doesn't exist ?

Thanks

Don K

head -1 is probably a lot more standard (I've been encountering a lot of GNU scripts lately that have made me crazy).

Perhaps if you set up your client-local.cfg entry like:

file:`find /Volumes/MySQL_Backups/ -name '*.sql' -mtime 0 2>/dev/null | sort -r | head --lines=1`

so that only the most recent file (by name) will be returned.

Thanks,

Hi folks. I've been trying to figure this out for a while and would appreciate any help.

I'm trying to monitor for a sql backup by watching for a set of files that are created every morning at 00:05 AM by a cron job on a server.
There are several files created each night the sql dump runs.
It creates them as filename_backup__yyyymmdd.sql
So each day there are new file names created (never the same name)
I want to alert if the file doesn't get created each day with the new name.

I have configured the client-local.cfg file as follows:
[MYSQLSERVER01]
# dir:`find /Volumes/MySQL_Backups/ -name '*.sql' -mtime 0 2>/dev/null`
# file:/Volumes/MySQL_Backups/mysql_backup_20121004.sql
file:`find /Volumes/MySQL_Backups/ -name '*.sql' -mtime 0 2>/dev/null`

Analysis.cfg is as follows:
HOST=MYSQLSERVER01
FILE %^.sql COLOR=red mtime<600
# FILE /Volumes/MySQL_Backups/mysql_backup_20121004.sql red mtime<600
# FILE /Volumes/MySQL_Backups/mysql_backup_20121004.sql COLOR=red mtime<600
# FILE /Volumes/MySQL_Backups/mysql_backup_20121004.sql red mtime>86400
# FILE /Volumes/MySQL_Backups/mysql_backup_20121004.sql red mtime<86400
# FILE /Volumes/MySQL_Backups/mysql_backup_20121004.sql red mtime>600
# FILE /Volumes/MySQL_Backups/mysql_backup_20121004.sql mtime>86400 noexist

Xymon generates this msg when I use the full filename – eg mysqlbackup20121004.sql in analysis.cfg
It doesn't work when I try to use a wildcard name (which I need because the filename will change each day) - eg FILE %^.sql

Example alert is below using full real filename:
Thu Oct 4 16:02:11 CDT 2012 - Files NOT ok

[red] /Volumes/MySQL_Backups/mysql_backup_20121004.sql<http://srmxymon.ambrosi.com/xymon-cgi/svcstatus.sh?CLIENT=MYSQLSERVER01&SECTION=file:/Volumes/MySQL_Backups/mysql_backup_20121004.sql>
File was modified 57134 seconds ago - should be <600


[green] /Volumes/MySQL_Backups/herbalife_backup_20121004.sql<http://srmxymon.ambrosi.com/xymon-cgi/svcstatus.sh?CLIENT=MYSQLSERVER01&SECTION=file:/Volumes/MySQL_Backups/herbalife_backup_20121004.sql>


Example below using %^.sql:

 Thu Oct  4 16:10:15 CDT 2012 - Files ok

[green] /Volumes/MySQL_Backups/mysql_backup_20121004.sql<http://srmxymon.ambrosi.com/xymon-cgi/svcstatus.sh?CLIENT=MYSQLSERVER01&SECTION=file:/Volumes/MySQL_Backups/mysql_backup_20121004.sql>[green] /Volumes/MySQL_Backups/herbalife_backup_20121004.sql<http://srmxymon.ambrosi.com/xymon-cgi/svcstatus.sh?CLIENT=MYSQLSERVER01&SECTION=file:/Volumes/MySQL_Backups/herbalife_backup_20121004.sql>
