XI: adjustments to support large deployments & APP backups

Ahoy folks, We maintain several Nagios XI instances within our ENVs (some large deployments, some small). For most of our ENVs, we can rely on either the built-in XI level "Scheduled Backups (Local Backups)" facility. This works well (for the most part), in that it seems to have a built-in...

XI: method to poll values for "Monitoring Engine Event Queue

Ahoy folks, We maintain several Nagios XI instances within our ENVs (some large deployments, some small). Through this, we have developed a sort of common interface for the "Dashboard" view of XI, which includes "Monitoring Engine Event Queue: Scheduled Events Over Time". In our ...

Re: XI: host templates and inheritance

Ahoy Perry (and team)! Thank you for the review on this matter, and suggestions. In the end, I managed to arrive to a successful configuration, that suits my users scenario. In short, it was a combo of your confirmation on gradual scope for templates ( General Template -> Linux-server -> MyHost ), a...

Re: XI: support for service definitions (with "parents" attr

Superb, and thanks for logging the FR on this matter. Also thank you for the notes you posted below, will pass those along to my users. Is there any good XI level references / docs for handling service dependencies? I had a look but it all seems to map back to nagios (core) level stuff, which I have...

XI: host templates and inheritance

Ahoy folks, At present we are making some use of host templates for basic UP/DOWN checks. Also took the advice early and made a series of CONTACT GROUPs to help manage notification targets. Specifically, the following: - generic host template for UP/DOWN - contains syntax for check_icmp command - ti...

XI: support for service definitions (with "parents" attribut

Ahoy folks, Some of my users (Openshift team) are looking at how they run their service monitors. Given the dynamic "ebb & flow" of hosts in their environment, they were asking after the notion of "parent/child" for service monitors. Essentially the same sort of thing that is...

Re: Nagios XI cannot read the /etc/passwd or /etc/groups fil

Many thanks, that gave me the "bread crumb" I needed! I completed this on my NFS filer, and then noted a different error (to do with the `apache` user having some sort of permissions issue). I thought to double-check and verified all was set from the NFS filer (`nagios:nagios` existed on t...

Nagios XI cannot read the /etc/passwd or /etc/groups file

Ahoy folks, I am working to setup a DR scenario involving two Nagios XI APP nodes and a shared NFS mount from an off-box NFS "filer" (basic VM with big disk attached / shared). In this present scenario I am using basic deployments of Nagios XI (stand-alone, all-in-one, out-of-box), with so...

Re: XI: NDO3 -- instability / poor performance at scale

Thank you for the steps below. FYI, we attempted this upgrade once again (using XI 5.8.2 release for this cycle). As with prior attempts, all went relatively well until we struck upon our "large" instance (as was described in the initial post). Initially NDO3 performance seemed to work som...

XI: NDO3 -- instability / poor performance at scale

Ahoy folks, We run multiple instances of Nagios XI to monitor my customer environments. This includes a split in an attempt to distribute load (EG: ACTIVE vs PASSIVE checks), where each instance is self-contained. These were all initially installed on the XI 5.6.x release series, on-top of RHEL 7.x ...
