Fabian Stäber from Instana, gives a really informative talk about how to tackle monitoring with microservices.
Lots of things to consider:
- Automation of monitoring to avoid bottlenecks with deploying microservices.
- The underlying data
More than health checks which are more common with monoliths.
Define what does it mean for my application to be healthy. Discussing how you take this time series data and apply it to the additional dimensions that microservices bring.
- Aggregation horizontal metrics
- Vertical checks – what is going on in the stack Java, JVM, Docker, K8 node, hardware itself.
- Ensure new and legacy services also provide tracing
- Tie together traces to error logs.
Fabian helpfully points out these three Site Reliability Engineering books from Google that are available for free.
- Simone Mainardi
- Tobias Appel
NB: Commercial repurposed hardware was used.
- Julien Pivotto
- Malcolm Holmes
Area of research, Jsonnet. Used to template JSON files. NB There was a talk re Kubernetes Jsonnet usage yesterday.
Aim to provide consistency and improve reusability of dashboards.
By Florian Lautenschlager & Robert Hoffmann
They are building a GDPR compliant voice assistant that give users control over personal data.
Lovely but not usable by their team.
How did they improve the usage and culture in their organisation to their monitoring toolkit.
E.g. Adding links from metrics re tests failing to system logs related to that test.
Create a dashboard to facilitate frequent queries, e.g. Search by trace id or username.
Also they integrated the links into commonly used tools, like ticket systems or chat tools.
