Should the documentation be different, or  version 2 has completely different commands set?  I am running latest pmm Agent on Centos and Ubuntu servers. On both, output for `pmm-admin check-network` and `pmm-admin` is the same: ```auto [root@server-3 centos]# pmm-admin check-network pmm-admin: error: expected command but got "check-network", try --help [root@server-3 centos]# pmm-admin usage: pmm-admin [] [...] Version 2.4.0 Flags: -h, --help Show context-sensitive help (also try --help-long and --help-man) --version Show application version --server-url=SERVER-URL PMM Server URL in `https://username:password@pmm-server-host/` format --server-insecure-tls Skip PMM Server TLS certificate validation --debug Enable debug logging --trace Enable trace logging (implies debug) --json Enable JSON output Commands: help [...] Show help config [] [] [] [] Configure local pmm-agent list [] Show Services and Agents running on this Node status Show information about local pmm-agent summary [] Fetch system data for diagnostics add mongodb [] [] [] Add MongoDB to monitoring add mysql [] [] [] Add MySQL to monitoring add postgresql [] [] [] Add PostgreSQL to monitoring add proxysql [] [] [] Add ProxySQL to monitoring register [] [] [] [] Register current Node at PMM Server remove [] [] Remove Service from monitoring ``` Am I doing something worng?  pmm-admin check-network is documented in Documentation for 2.4  Section 3.4 _To make sure that the new server is available run the pmm-admin check-network command from the computer where PMM Client is installed. Run this command as root or by using the sudo command_ ---

Hi @“Arnis Juraga”, `pmm-admin check-network` is not a valid v2 command. Can you send the link to the documentation you mention? ---

The official one! Open documentation, search for “check-network”. You will find. To be honest, I tried pmm2.4 and had multiple problems, starting from installation documentation issues. Anyway - the problem for me was, that machine was registering successfully on my DOCKER installation, clients registered visible in Dashboard, but later not receiving any data. So I followed debugging (troubleshooting) and that documentation is very outdated then for 2.4… All are official links: [https://www.percona.com/doc/percona-monitoring-and-management/index.html](https://www.percona.com/doc/percona-monitoring-and-management/index.html) Select “PMM 2” on the left side dropdown.  [https://learn.percona.com/hubfs/Manuals/Percona\_Monitoring\_And\_Management\_PMM/PMM-2.1/PerconaMonitoringAndManagement%202.4.0.pdf](https://learn.percona.com/hubfs/Manuals/Percona_Monitoring_And_Management_PMM/PMM-2.1/PerconaMonitoringAndManagement%202.4.0.pdf) ---

@“Arnis Juraga”, Thanks for the details, I’ll check the link you sent with the team, and create a new bug report for it, if needed. For any other incorrect (or incomplete) documentation sections, feel free to open a documentation bug in [https://jira.percona.com/projects/PMM/issues](https://jira.percona.com/projects/PMM/issues "Link: https://jira.percona.com/projects/PMM/issues"). Regarding the lack of metrics, did you also check the client-side logs? ```auto journalctl -u pmm-admin ``` ---
