Hello ! I'm a beginner and I might have missed something important. Elasticsearch is not returning any system metrics when I'm invoking the following command ```auto GET _cat/nodes?v=true ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name 172.18.0.3 cdfhilmrstw * 7d4ef3d44bd2 ``` The only value returned is heap.max (probably defined statically). Installation is **Docker based** (official image) ```auto }, "versions": [ "8.5.1" ], "os": { "available_processors": 5, "allocated_processors": 5, "names": [ { "name": "Linux", "count": 1 } ], "pretty_names": [ { "pretty_name": "Ubuntu 20.04.5 LTS", "count": 1 } ], "architectures": [ { "arch": "aarch64", "count": 1 } ...snip... "jvm": { "max_uptime_in_millis": 225101686, "versions": [ { "version": "19.0.1", "vm_name": "OpenJDK 64-Bit Server VM", "vm_version": "19.0.1+10-21", "vm_vendor": "Oracle Corporation", "bundled_jdk": true, "using_bundled_jdk": true, "count": 1 } ], ``` Is there anything I'm missing ? Thank you. ---

Hi @ben75020 Welcome to the community... Hmmmm What OS are you running this on? ```auto "architectures": [ { "arch": "aarch64", "count": 1 } ``` What does this return `GET /_nodes` Or `GET /_nodes/jvm,os` ---

Yes I understand it's Mac OS and official docker image What I was asking if is this the new M1/M2 ARM chip? My Mac is intel-based Is your Mac the new M1/M2 ARM Chip? If so, perhaps it _is_ a bug .. or not... not sure... and I could not test that any ways. Also do you have your docker desktop up to date? Did you run this? `GET /_cat/nodes/?v&h=name,du,dt,dup,hp,hc,rm,rp,r` And What curious exactly are you trying to solve... those values are point in timeso not really good for anything other than a quick look, if you want to monitor elasticsearch there are other approaches ---

> What I was asking if is this the new M1/M2 ARM chip? Sorry, I did not understood the question at first round 🙂 This is a Mac-M1.

I know that they are best approaches (we are using datadog collector, in example, at work), but I'm testing several things offered into the documentation. My message was also to ensure I did not miss a critical software component installation while setting up my lab cluster. Ultimately, what I was trying to achieve, was getting an activity indicator per role (my current container has all possible roles), in order to identify if (and when !) it's required to dedicate some additional nodes for specific task (in example : ingestion). ---

I know that they are best approaches (we are using datadog collector, in example, at work), but I'm testing several things offered into the documentation. Very cool you are getting to know / learning elastic. Looks like a great book to get started but be careful, it is Published July 2021 which means the actual information is nearly 2 years old there is _ **HUGE HUGE** _ changes since then and Elastic 8.X (we are currently 8.5.3 and soon to be 8.6) is very different than 7.x I would highly recommend augmenting your reading with our [official documentation](https://www.elastic.co/guide/index.html) / [blogs](https://www.elastic.co/blog/) / [free training](https://www.elastic.co/training/free) etc. > [@ben75020](#): > > My message was also to ensure I did not miss a critical software component installation while setting up my lab cluster. Its Possible there is a bug... will need to check into that ... Also to get some feature monitoring to work you may need to specify the resource limits in your docker compose. ```auto deploy: resources: limits: cpus: '0.50' reservations: cpus: '0.25' ``` > [@ben75020](#): > > However, top is able to retrieve system metrics. > [@ben75020](#): > > I know that they are best approaches (we are using datadog collector, in example, at work), but I'm testing several things offered into the documentation. Whoa 🙂 No need to use Data Dog, [Elastic is a 1st Class Observability Platform](https://www.elastic.co/observability) this has evolved greatly in the last 2 years! We are a recognized leader in AIOps etc. [Metricbeat](https://www.elastic.co/guide/en/beats/metricbeat/current/index.html) will collect 100s of metrics for both the host system and docker containers and elasticsearch To get System, Docker and Elasticsearch Monitoring just enable the modules ... Download Metricbeat and untar it on your mac. Assuming you just used all the defaults Enable the modules (System is enabled by default) `./metricbeat modules enable docker elasticsearch-xpack kibana-xpack` then setup `./metricbeat setup -e` The start metricbeat `./metricbeat -e` And you will get Host, Docker and Elasticsearch will show up under Stack Monitoring. See Below for images. We also have the new Elastic Agent ... which is 1 Agent for Observability, Security and Even free endpoint protection. Enjoy, Come back with more questions..

Thanks Stephen for your exhaustive answer. If I can help with anything about bug reproduction/opening, let me know. The book I'm following is the second edition, not yet published (this is the "MEAP (Meaning Early Access Program)". It covers some (may be not latest) ES 8 features. I'll give metric beat a try very soon. > [@stephenb](#): > > Enjoy, Come back with more questions.. I do have one in mind, I'll open another thread later to present it. Thank you ---
