(Customers that already have a Nagios server running on Linux won’t need the last two Linux items in that list - they will just need the AAG Nagios plug-in developed by Shield.) The three Linux components consists of the AAG plug-in for Nagios, which receives data from NG4i a copy of the open source Nagios Core server and a pre-built Linux image. According to Hird’s November 17 blog post, this component includes a TCP/IP server. On the IBM i server, AAG consists of NG4i, which was developed by Shield and is in charge of collecting data from IBM i and feeding it to the Nagios plug-in (which runs on Linux). The AAG offering consists of several components, including one that runs on IBM i and three that run on Linux. The result of this effort is AAG, which Shield unveiled in late November and is now selling access to via subscription. That ended after a number of problems and gotchas made it impossible to guarantee a level of support we would be happy with for our customers.”įaced with dead-end third-party Nagios solutions, Hird took the time-honored approach and decided to build his own. “We did build a NEMS for Linux appliance (with little help from the developer) that included the IBM-provided plug-in. “We found them to be lacking in many areas, and support from IBM for theirs was not great,” Hird tells IT Jungle via email, adding that most of the technical support came from China and was not timely. However, when Shield Advanced Solutions president Chris Hird started working with the IBM offerings (as well as a couple of other open source Nagios products developed by the community), he was not particularly impressed. IBM rolled out a Java-based Nagios plug-in back in 2018 that collects and feeds IBM i server metrics into Nagios Core or Nagios XI, two open source Nagios packages that run on Linux. Today it’s being used to keep an eye on just about anything in the data center via thousands of available plug-ins, including ones that monitor IBM i servers and the applications that run on it. The software was originally developed in 2002 to monitor Linux systems, and over the years, its usage has grown considerably. Nagios is a free open-source software project that provides monitoring and alerting for servers, networking devices, applications, and other IT gear. Dubbed AAG, for At A Glance, the product currently monitor 65 IBM i parameters, and can be used with existing Nagios deployments running on Linux or deployed in a standalone manner with an included Linux runtime. Shield Advanced Solutions last week rolled out a new system monitoring solution based on open-source Nagios technology that gives customers quick insight into the state of their IBM i server.
