Previously we looked at how to use the Prometheus Alertmanager with Pagerduty. The Alertmanager supports more than just sending pages, there's integrations with popular chat applications too. Let's look at how to integrate with Slack.
Prometheus labels allow you to model your application deployment in the manner best suited to your organisation. As directly supporting every potential configurations would be impossible, we offer relabelling to give you the flexibility to configure things how you'd like.
The new Alertmanager has integrations to a variety of popular notification mechanisms, one of those is PagerDuty. Let's see how easy it is to hook it in. Read more
The rewrite of the Alertmanger had its first release earlier this week after a beta period. While still providing the core functionality of deduplicating alerts, silencing, inhibiting and sending notifications, there's several major changes from the previous version.
Prometheus offers a number of ways to find the targets to scrape, DNS, EC2, Consul, Kubernetes, Zookeeper and Marathon. But what if what you aren't using one of those?
Prometheus isn't limited to monitoring just machines and applications, it can provide insight for any system you can get metrics out of. That includes network devices, so let's look at how to monitor SNMP.
I previously looked at how the Prometheus Python client can output to Graphite. You can do the same with the Java client, letting you instrument once and integrate with non-Prometheus monitoring systems.
As part of designing and building Prometheus, hundreds of technical decisions have to be made. Every one of them is important in building a sustainable consistent ecosystem. Today, let's look at one small decision that was made by the Prometheus developers in Consul service discovery.
