Support forum for Nagios Core, Nagios Plugins, NCPA, NRPE, NSCA, NDOUtils and more. Engage with the community of users including those using the open source solutions.
At this time, I do not see a plugin specifically for EJBCA. However, I did notice a post that you may be able to query it through snmp either with default or by creating custom oids. See what you think of this article.
Nagios-Plugins maintainer exclusively, unless you have other C language bugs with open-source nagios projects, then I am happy to help! Please pm or use other communication to alert me to issues as I no longer track the forum.
