Nagios Support Forum

Hi,

I have two Solaris servers that NCPA are both on maintenance.


svcs | grep ncpa
maintenance Oct_14 svc:/site/ncpa_passive:default
maintenance Oct_14 svc:/site/ncpa_listener:default


I tried to clear and refresh the service


svcadm refresh ncpa_passive
svcadm clear ncpa_passive


I check the logs on /var/svc/log/site-ncpa_listener:default.log

Do I need to install the zlib to fix the issue?
This is the version I use to install the NCPA (ncpa-2.4.0.sol11.i86pc.pkg)

Thank you.

Hi Nagios Support,

Would like to follow up on this please.

Hi @alakian, thanks for reaching out.

NCPA 2.4 has known issues on Solaris. Most Solaris users have success using NCPA 2.3.1.

The forums are for community driven assistance and sharing of tips and techniques for working with Nagios Products. If you need urgent assistance with a Nagios Product please create an Answerhub case.

NCPA itself is an opensource community driven project and official support for Solaris is no longer being provided. If you would like to work on porting version 3.0 to Solaris you can find a link to the project here: NCPA

As well as the issues page here: NCPA Issues

And the Solaris specific issues here: NCPA Solaris Issues

You can try to install the `zlib` package using `pkgadd -d SUNWlibs zlib` and restart the NCPA service with `svcadm restart svc:/site/ncpa_passive` to resolve the issue. fnf
