We have talked about a few important tools for monitoring Microservices. There are additional tools one can consider based one's need. Splunk can be used for logging, indexing, and fetching information, somewhat similarly to ELK. Fluentd can be used to implement a logging layer. Logspout can be used to collect and forward logs. We already looked at Zipkin and OpenTracing for tracing; some similar tools are Appdash and Phosphor. We talked about alerting with Prometheus, but you can use other tools, such as PagerDuty, for alerting. For simple checks, such as service availability, try Pingdom.

In addition, if you are using a cloud service provider, such as Amazon Web Services, Google Cloud, or Microsoft Azure, you might get some tools out of the box, which will help you monitor and manage your Microservices.

A complete discussion on all these tools is outside the scope of this chapter, but the information shared should give you an idea of the core concepts and considerations you need to be aware of when you implement monitoring for Microservices-based applications.
