Different Results

[rahul2gupta]

Hi,

We are facing one unprecedented error here.When we run the script in one of the client machine it shows the following results.

[root@aagwmapeai339 ce]# sh check_eai_sap_transaction_manager_cleanup.sh
0
EAI SAP TransactionManager Cleanup is normal

While when we run on the main server its shows different:

[root@aeaginfkon01 libexec]# ./check_nrpe -H aagwmapeai339 -c check_transaction_manager_cleanup
1
EAI SAP TransactionManager Cleanup is normal

Can you please guide us how to overcome this problem?

Regards,
rahul

Hi rahul,

Thanks for posting to the Community Forum. I believe this might be an issue with the script itself. Was this script downloaded from the Nagios Exchange or did you write it?

Also, I would test the plugin using the nagios user account as that's how it will run.

Hi,

We wrote the script. It is not the one downloaded from Nagiosn exchange.

Following is the script.

cat /home/ansible/server.log|grep "TransactionManager: Deleting transactions:"|grep "00:00" && echo "EAI SAP TransactionManager Cleanup is normal"

When we execute the script on client machine we are getting expected results.

[root@host1 nrpe.d]# sh /usr/lib64/nagios/plugins/ce/check_eai_sap_transaction_manager_cleanup.sh
2020-10-19 00:00:00 AEDT [SAP.0110.0021I] (tid=486877) TransactionManager: Deleting transactions: 610 deleted.
EAI SAP TransactionManager Cleanup is normal

but when we invoke it from Nagios server, it is giving error.

[root@nagios libexec]# ./check_nrpe -H host1 -c check_transaction_manager_cleanup
NRPE: Unable to read output


Following is the entry in nrpe.cfg file

command[check_transaction_manager_cleanup]=/usr/lib64/nagios/plugins/ce/check_eai_sap_transaction_manager_cleanup.sh

We tried executing the script using nagios user on client machine. we are getting expected resunts.

[root@host1 nrpe.d]# su - nagios
