op5 Monitor is a highly scalable solution and enables you to setup distributed monitoring with automatic fail-over, load-balancing and redundancy. In this 30 minutes webinar we will give you insights on why and how to scale op5 Monitor to your needs.
This howto describes how to recive SNMP-Traps with op5 Monitor.
This howto will describe how you use Event Handlers with op5 Monitor to let monitor take action upon an event, for an example restart a service on a certain state-change.
In this How-To we will be using a small perl script that uses the op5 Monitor plugin called check_http to graph the response time of a webserver. All commands in this How-To are executed in an ssh connection at the op5 Statistics server.
This how-to describes how to setup your op5 Monitor server with Oracle Instant Client to be able to use check_oracle directly towards the Oracle Database without the need of 3rd party agents.
Monitoring with WebInject is about testing a real-world scenario. If you measure web server response time simply by requesting / you might miss the delay when the database is doing a large select during the login process, and if you only monitor that the database server is up and running you might still miss the less common problems the web server might have while connecting to the database.
With WebInject, you can actually try out the entire login process, evaluate that the page doesn't contain error messages or that the latest news show up. You can also measure the entire time it takes to log in – which on many sites can be as much as half a minute although the web server serves each page in just a couple of milliseconds.
Any monitoring system, including op5 Monitor, needs to be adjusted to suit your organizations specific needs. This how-to describes the basics of identifying the source(s) of your notifications and adjusting thresholds and configuration to get rid of false/uninteresting or exaggerated alerts ("alarms"/notifications). A new installation definitely needs tuning, but it's also a good idea to generate reports on a regular basis to prevent being flooded with notifications
