TSMmonitor

Introduction

This script is developed to provide an easy, customizable and effective way to monitor IBM TSM - (Tivoli Storage Manager) Servers.

It is composed of functions to check specific TSM resources. Each check returns the resource status. The available status for a resource are:

Ok / Warning / Critical

The status returned is based on defined thresholds for each check. For example, the function to check the TSM Database utilization:

        prompt> ./tsmmonitor db -h

        check tsm database utilization

        The default percentages are:
           warning..: 85
           critical.: 90

        Usage..: tsmmonitor db [options] [warning] [critical]

                 -v6     check database utilization for TSM version 6

        Usage..: tsmmonitor db [warning] [critical]
        Example: tsmmonitor db
                 tsmmonitor db 80 95
                 tsmmonitor db -v6 80 90

The status returned from db check depends on the warning and critical threshold values. These values can be customized using command line arguments:

        prompt> ./tsmmonitor db
        db: database utilization 81%, OK

        prompt> ./tsmmonitor db 80 90
        db: database utilization 81%, Warning

        prompt> ./tsmmonitor db 60 80
        db: database utilization 81%, Critical

Some nice features:

Supports multiples tsm servers (servername)
Can be used transparently as a nagios plugin
Alert notification mechanism (by e-mail)
Customizable threshold values for ok/warning/critical status in command line
Bourne shell (sh) compliance
Easy to add news checks

This script should work fine under most *NIX variants. It has been tested successfully under many Linux and AIX (4.3, 5.2 and 5.3). If you have any problem, please let me know.

Changelog

Version 2.2, released on 07/11/2012 (DD/MM/YYYY)

added support for TSM 6 for db and log checks
dbbkp - replaced sed by egrep. AIX sed does not have OR oper

Version 2.1, released on 11/09/2009 (DD/MM/YYYY)

added falseprivate check
fixed bug drmvol

Version 2.0, released on 28/11/2008 (DD/MM/YYYY)

the source code was rewritten.
there were changes on the command line options, so version 2.0 BREAKS BACKWARDS COMPATIBILITY.

Version 1.0, released on 15/06/2007 (DD/MM/YYYY)

First public version

Download

Just download file: tsmmonitor

Using it is quite simple. It doesn't require installation. All you have to do is set three options in the source code. Edit the script and look for this section:

############### tsm server information
#
# dsmadmc command path
DSMADMC='/usr/bin/dsmadmc'

# tsm user to connect to the tsm server and perform the checks
USER=''

# tsm user password
PASS=''

Only these variables must be changed. If everything is fine, you can now test the script:

prompt> tsmmonitor --help
prompt> tsmmonitor db

Take a look at the source code for more customizations.

TSMmonitor in Action

Some samples to show tsmmonitor in action:

prompt> tsmmonitor -h
Usage: tsmmonitor [options] [check] [options_check]

Options

-u, --user          tsm user to connect to the tsm server
-p, --pass          tsm user password to connect to the tsm server
-s, --servername    specify tsm servername
-m, --mail          mail addresses separated by blank space
-q, --quiet         quiet mode, suppress all output (except errors)
-S, --source        print the check source code
-h, --help          print this help information and exit
-V, --version       print program version and exit

The following checks are available:

help, db, log, scratch, drive, path, dbfrag, unav, stgpool, volerr,
volreclaim, tapeslib, tapesown, tapesstgpool, dbbkp, numsess, numnodes,

Try 'tsmmonitor <check> --help' for more information.

Example:
    tsmmonitor db --help
    tsmmonitor db
    tsmmonitor db -v6
    tsmmonitor -m='user1@somewhere.com user2@somewhere.com' db
    tsmmonitor --servername=tsmsrv01 db
    tsmmonitor --servername=tsmsrv02 db 85 95
    tsmmonitor -u=user1 -p=xxx -s=tsmsrv02 db 85 95

Showing the help of db check:

prompt> tsmmonitor db -h

check tsm database utilization

The default percentages are:
   warning..: 85
   critical.: 90

Usage..: tsmmonitor db [warning] [critical]
Example: tsmmonitor db
         tsmmonitor db 80 95

Checking the TSM database utilization:

prompt> tsmmonitor db
db: database utilization 79%, Ok
prompt> echo $?
0

Checking the TSM database utilization specifying different percentage for warning and critical status:

prompt> tsmmonitor db 70 85
db: database utilization 79%, Warning
prompt> echo $?
1

prompt> tsmmonitor db 60 75

Nagios Plugin

TSMmonitor can be used transparently as a nagios plugin. Nagios plugins are based on script return code:

0 - normal
1 - warning
2 - critical
3 - unknown

These are the same return codes used by TSMmonitor.

Alert Notification

You can use the alert notification to receive an e-mail when the status changes. This feature is disabled by default. To turn on, you have to change the following options in the source code:

############### send notification
#
# at every time that a check changes the status,
# an alert (notification) will be sent by mail. default is off
SEND_ALERT=0   # 1 = on and 0 = off

# e-mails which will receive the notifications. mail addresses are separated
# by blank space. ex: MAILTO='xxx@yyy.zzz aaa@bbb.zzz ppp@qqq.lll'
MAILTO=''

# temp directory where tsmmonitor will record check status.
# it is necessary to send mail when the check status changes
TEMPDIR='/tmp'

Remeber you can specify different mail addresses in the command line:

prompt> tsmmonitor -m=user2@somewhere.com db

You can use the cron to execute scheduled checks and receive the tsmmonitor alerts by e-mail.

prompt> crontab -l
*/15 * * * *    /PATH/tsmmonitor db      > /dev/null
*/10 * * * *    /PATH/tsmmonitor log     > /dev/null
*/10 * * * *    /PATH/tsmmonitor drive   > /dev/null
*/10 * * * *    /PATH/tsmmonitor path    > /dev/null
*/15 * * * *    /PATH/tsmmonitor scratch > /dev/null
