UserParameter Permission denied

[miramira007]

Hey all,

sorry for asking such a dummy question. But yet i haven't got anyone to ask. Maybe someone here can help me.

I want to monitor a deamon in centos via UserParameter.

To testing i created in server x zabbix agent a UserParameter, which looks like this here:

UserParameter=services.check.name, sudo systemctl status name | grep -c running

Gave zabbix all privilegies via visudo. the copy is here:

zabbix ALL=(ALL) ALL

I know it isn't the best way (maybe the dirtiest one, but this all is just a testing now)

After creating an item, i have got an error. This one:

sh: /usr/bin/sudo: Permission denied
0

What should i do? I haven't got an idea, where the problem can be.

I think i made a mistake in the sudoers file? First i edited it with nano! Maybe this can be the reason?

Thanks a lot,
mira

Hi,

Few suggestions:
1. Try editing the file with command "visudo"
2. Instead of zabbix ALL=(ALL) ALL add the following line:

zabbix ALL = NOPASSWD: /sbin/systemctl

Otherwise it will still ask for password when executing this command.

Hope this helps!

Best Regards,
Ingus

Thank you for your answer,

i edited the sudoers file with visudo like your suggestion, but it hasn't changed anything

Maybe an other idea? My Zabbix Server and Agent are running on a CentOS 7. Both are in version 2.4.7.

If possible, temporary disable SELinux and try again if that helps.

setenforce 0

Then check /var/log/audit for zabbix agentd related errors. Create policies if needed.

For testing i disabled SElinux,
added this in /etc/sudoers

Defaults: user !requiretty

And now it works.

Im such a dummy! I know i havent got to say it, because you can notice that from my question!

Thanks a lot.
