Hello @sacom01

Thanks for reaching out, in test the 'unix_check_ping.py command we see that it is pulling the list of hosts to check from:

• '/usr/local/ncpa/plugins/host.txt'

Please verify that the list of hosts are included and that it the owner/group on host.txt is readable.

The command to run:
I used

python3 unix_check_ping.py
and resulted in: All hosts available

Thanks,
Perry

hi,
i tried chmod 777 for host.txt but no luck, still facing issue.

Hello @sacom01

Thanks for following up, appears that we receive "Host is not available". Wondering if the host is pingable?

I want to verify that you are able to ping the device/host.
Thanks,
Perry

hi Perry,
the problem is no host unavailable, all hosts able to ping. You can see the picture, it show alert without any host.
thank you.

Hello @sacom01

Thanks for following up, and want to see what the verbose event logging on this looks like.
Please provide the results so we can further review.

Thanks,
Perry

hi Perry,
pls find attach file for detail.
thank you

Hello @sacom01

Thanks for following up and providing the verbose results on the 'unix_check_ping.py command.

After review I am totally perplexed because we don't see anything failing other than the fact that we receive a 'Critical -Host is not available' warning message. You stated in the previous post that you are able to successfully ping the host. Are you pinging via FQDN or IP Address; please verify both are reachable and resolve (DNS).

Let's go ahead and download and try the 'check_ping_ip_list_file.sh' from the plugin exchange. With many options to alter the script to your liking if you decide to use it.

Example: Please let us know the results,
Perry

hi Perry,
the service work fine now. i have to filter row by row in host file. Maybe it have strange character or anything.
Many thanks for your help.
pls close topic.

Hello @sacom01
