Monitoring shell scripts

[higi]

Hi,

what i want to do is to monitor some of our shells scripts.
for example simple backup scripts:

backup_mongo.sh

#!/bin/bash
TIME=`date +%Y-%m-%d`

mongodump --host localhost --port 27017 --db mongo --collection profilInstance --out - | gzip > /opt/backup_local/mongodb_$TIME.gz

backup_postgresql.sh

#!/bin/bash
TIME=`date +%Y-%m-%d`

pg_dumpall -h localhost -p 5432 -U postgres > /opt/backup_local/all_$TIME.gz

What i want todo is to monitor if script backup_mongo.sh / backup_postgresql.sh finished successfully.
Create "Graph" where i can see every day marked that mongo/psql was finished 1(ok) / 0 (failed)
Create "Trigger" so it will send warning if mongo/psql was finished 0 (failed)

Was googling like few hours and i wasnt able to do it properly. (i am a noob) Please dont post any links to stackoverflow etc, saw them allready. (still i couldnt get it working)

If can anyone please post real "step by step guide"(for noobs like me). Including changes to my shell scripts, what to do on client (agent) side and Zabbix server side.

Or maybe someone can help me to setup it on teamviewer.

THX for any HELP.

(sorry my english is bad)

I have a question, how you execute your scripts on the host? It is in crontab or anything like this?

You can use error code if it provided by dump utils. You can use zabbix_sender for this. Just add to your script somth. like this:

echo $? > dmputil.err
<path_to>/zabbix_sender -z <zabbix_server_ip> -i dmputil.err

Look here: https://www.zabbix.com/documentation.../zabbix_sender

crontab
# m h dom mon dow command
20 23 * * * su -l postgres -c "/opt/_shell/_psql_backup.sh > /tmp/psql_backup.log" 2>/dev/null
54 2 * * * /opt/_shell/_mongodb_backup.sh
35 23 * * * /opt/_shell/_jackrabbit_backup_gz.sh
* 22 * * * /opt/_shell/_renewssl.sh

Before make any change in your files (config/scripts) do a backup of the working files.

Well one way to monitor the status of your shell scripts is by UserParameter.
First you need to write de status of your script to an log file.
Ex.:

#!/bin/bash
TIME=`date +%Y-%m-%d`

mongodump --host localhost --port 27017 --db mongo --collection profilInstance --out - | gzip > /opt/backup_local/mongodb_$TIME.gz
echo $? > /var/log/mongodb_bkp.log

Then you can set an UserParameter to read this file (in the host that execute the backup), UserParameters need to be defined in zabbix_agentd.conf.
Ex.:

echo "UserParameter=mongodb.bkp.status,cat /var/log/mongodb_bkp.log" >> /path/to/zabbix_agentd.conf

Then the last step is create an item in your Zabbix Server (the item may be created in the host that the backup run).
The Item will have the key that we defined at second step (mongodb.bkp.status).

All os this steps you can search at Zabbix Documentation, but if you have any trouble msg me!
