Check_MK_Agent.hpux (HPUX)

[Gustavo]

CMK version: 2.0.0p17 (CRE)
OS version: Centos7

Hi,

I would like to install the check_mk_agent on HPUX B.11.31, i see these agents on Agents - Other Operating Systems:

Regarding the

Can some one tell me if i can use this ? and the process to install the agent?

Thank you!!

Perhaps not the “right way”, but I setup the host with no agent and set up a rule for “Individual program call instead of agent access”, with an ssh call where the end user (via key in authorized_keys) executes the check_mk_agent.hpux program.

Hi @cjcox

Thank you for the information. could you please show me your configuration ?

And thank you.

Hi @Gustavo,

Were you able to go around setting up check_mk_agent service on your HP-UX node?
I too am struggling to setup one.

I did follow the discussion at - [Check_mk (english)] Installing check_mk agent on HPUX Unix - #7 by Marcel

But, I am unable to discover any services on the HP-UX node, even when I am able to reach port 6556.

Regards,
Abhijit

Hi, yes

I create a SOP for the steps that i use, but with the hpux agent you can do it.

Process/Steps:

Please follow the following steps to install the CMK Agent on OS: HP-UX

First, copy the file check_mk_agent.hpux to:

/usr/bin/ and rename it to check_mk_agent

After that, change the current permission to:

chmod 754 /usr/bin/check_mk_agent

and

chown root:sys /usr/bin/check_mk_agent

Corroborate these two directories on the check_mk_agent, and created if needed and give the current permissions:

export MK_LIBDIR="/usr/lib/check_mk_agent"
chmod 755 /usr/lib/check_mk_agent
chown root:sys /usr/lib/check_mk_agent

export MK_CONFDIR="/etc/check_mk"
chmod 755 /etc/check_mk
chown root:sys /etc/check_mk

To configure inetd, edit the file /etc/inetd.conf adding these lines at the bottom of the file:

#Check_mk
check_mk_agent stream tcp nowait root /usr/bin/check_mk_agent check_mk_agent

Edit the file /etc/services and add this line to listen on TCP port at the bottom of the file:

check_mk_agent 6556/tcp #check_mk agent

Finally, restart Inetd :

/usr/sbin/inetd -c

Test

To corroborate that the agent is already working:

telnet x.x.x.x 6556

@Gustavo

check_mk_agent

Thanks so much for sharing the steps.

Now, when “telnet x.x.x.x 6556” to hp-ux node works fine from cmk server, cmk discovery fails with below error message and accordingly service discovery in checkmk portal times out with “API Error:Your request timed out after 110 seconds.”:

SNMP Error, Agent OK

For the love of Cthulhu! Use code blocks, I beg you!

[Gustavo]

Sorry @abhiderle

I don’t know why you are seeing that error message, in my case works fine, both cases, telnet and discovery.

If you have another HPUX maybe you can try the same configuration and then see if it’s working well and reply on the first HP-UX.

I’m not an expert in this OS but maybe you can check if you can configure an SNMP configuration without agent and see what happens, but as I said, I’m not an expert, I don’t know to be honest if a SNMP config can be implemented

Please let me know if you can solved and how

Good wishes!

[robin.gierse]

You have the vSphere special agent enabled for that host, which obviously makes no sense on HPUX. That’s what is causing the error.
