You can look out for Prometheus Instrumentation (https://prometheus.io/docs/practices/instrumentation/) Client Library available in various languages https://prometheus.io/docs/instrumenting/clientlibs/ to create the custom metric you need for AS4000 and then Grafana can query the newly instrumented metric to show on the dashboard.

If you're already using Prometheus for your system metrics, then it seems like standing up Elasticsearch just for Linux host monitoring is excessive. The node_exporter is probably sufficient if you'e looking for standard system metrics.

Another thing to consider is that Metricbeat / ELK use a push model for metrics delivery, whereas Prometheus pulls metrics from each node it is monitoring. Depending on how you manage your network security, opting for one solution over two may make things simpler.

Hi Sunil! Unfortunately, I don´t have much experience with Metricbeat so I can´t advise on the diffs with Prometheus...for Linux server, I encourage you to use Prometheus node exporter and for PCF, I would recommend using the instana tile (https://www.instana.com/supported-technologies/pivotal-cloud-foundry/). Let me know if you have further questions! Regards Jose

We had a similar challenge. We started with DynamoDB, Timescale, and even InfluxDB and Mongo - to eventually settle with PostgreSQL.

Druid is amazing for this use case and is a cloud-native solution that can be deployed on any cloud infrastructure or on Kubernetes. - Easy to scale horizontally - Column Oriented Database - SQL to query data - Streaming and Batch Ingestion - Native search indexes It has feature to work as TimeSeriesDB, Datawarehouse, and has Time-optimized partitioning.

if you want to find a serverless solution with capability of a lot of storage and SQL kind of capability then google bigquery is the best solution for that.

Each of these tools can help you with micro service workload and work well. I will try to go through some good, bad and ugly of each.

Datadog has an easy setup and time to get something tangible out of it. The cost model is by host so this is something to take into consideration how it will affect your use case. Also as a large organization at some point you will probably want control over some/all of your telemetry data to run your own ML or AI processes. With Datadog you this can be difficult as you will need to create processes outside of its closed eco system to get Raw metrics.

Prometheus is a great tool. It also has a fairly straight forward setup especially with Kubernetes. If you are running your micro services in k8s then this is going to get used one way or another; it is a first class citizen there with heavy utilization of K8s API. I also like the fact that Kubernetes architecture is easy to understand and that it utilizes Grafana for the visualization engine. Prometheus at scale can be done but it is a pain. Especially with a distributed infrastructure across multiple workloads.

Influxdb (TICK stack in v1) is known for its scalability and flexibility as a time series database. Telegraf is the main input/data-forwarder of the architecture and is completely decoupled from the database as are the other 3 components of the stack. Influx has made it very easy to just use one component on its own. I have worked on stacks that just used telegraf for ingestion into Kinesis or another data stream. I have also worked on stacks that used Influx database but used a different ETL process for analyzing the data in realtime instead of using their v1 architectures Kapacitor query engine. Influx database is a great performing time series database that in version 2 runs within kubernetes and utilizes Flux as the query language. Flux is a nice query language that is fairly easy to learn and has a lot of flexibility. As a last positive note Telegraf is written in Go so that would fit well with your current team.

The difficulties of Influx are that it is hard to get something really tangible out of it. Initial time to see something is fast but all the other work involved is a lot. You also have to understand the architecture well. The management of Influx can be cumbersome but it can scale up better than the other two when Datadogs cost is taken into consideration. They have a lot of API hooks in their V1 enterprise edition to wire and configure it. They do offer a mange service to offload this cost until later.

My overall choice here is probably to go with some of the influx as you can rip and/or add components as needed into the flow. Eventually you will probably want to run an ML process within there (can be done within Kapacitor but of course can also use your cloud provider here too) and this gives you the flexibility to do it anywhere. I would still go through prometheus because you will most likely use it also, but it does have forwarders to Influxdb so still fits.

We're running Prometheus/Alertmanager/Grafana across our whole company for any monitoring and metrics requirement, from the infrastructure layer all the way up to Springboot endpoint services, the prometheus exporter / scraping approach works pretty well for us. It's really easy to setup and more importantly; to maintain it without much effort, all the Prometheus configs get automatically created through Terraform outputs and Ansible jobs. Combine it with Grafana and you're smiling.

We're moving towards Prometheus from Datadog at this moment. Main driving force is TOC at the moment.

Datadog is great until it becomes too expensive.

this is quite affordable and provides what you seem to be looking for. you can see a whole thing about the APM space here https://www.apmexperts.com/observability/ranking-the-observability-offerings/

I worked with Datadog at least one year and my position is that commercial tools like Datadog are the best option to consolidate and analyze your metrics. Obviously, if you can't pay the tool, the best free options are the mix of Prometheus with their Alert Manager and Grafana to visualize (that are complementary not substitutable). But I think that no use a good tool it's finally more expensive that use a not really good implementation of free tools and you will pay also to maintain its.
