[ NetData ] [ 1.23.0] Real-time performance monitoring, done right

Post by QNAP_Stephane » Wed Mar 30, 2016 8:41 pm

Source : https://github.com/firehol/netdata
demo : http://netdata.firehol.org

Download :

https://qnapclub.eu/fr/qpkg/285 x64

https://www.qnapclub.eu/fr/qpkg/882 Static version (built with musl) x86, x64, armv7, arm64

Note :

listen on port 9119

Feature :

netdata is a highly optimized Linux daemon providing real-time performance monitoring for Linux systems, Applications, SNMP devices, over the web!

It tries to visualize the truth of now, in its greatest detail, so that you can get insights of what is happening now and what just happened, on your systems and applications.

This is what you get:

Beautiful out of the box bootstrap dashboards
Custom dashboards that can be built using simple HTML (no javascript necessary)
Blazingly fast and super efficient, written in C (for default installations, expect just 2% of a single core CPU usage and a few MB of RAM)
Zero configuration - you just install it and it autodetects everything
Zero dependencies, it is its own web server for its static web files and its web API
Extensible, you can monitor anything you can get a metric for, using its Plugin API (anything can be a netdata plugin - from BASH to node.js)
Embeddable, it can run anywhere a Linux kernel runs

Ah, there are some errors there:


[~] # cd /opt/NetData/bin/
[/opt/NetData/bin] # ./netdata -p 9119
16-03-30 19:45:47: ERROR: netdata: Cannot open file '/opt/NetData/etc/netdata/netdata.conf' (errno 2, No such file or directory)
16-03-30 19:45:47: ERROR: netdata: IPv6 socket() failed. (errno 97, Address family not supported by protocol)
16-03-30 19:45:47: ERROR: netdata: IPv4 bind() failed. (errno 98, Address already in use)
16-03-30 19:45:47: FATAL: netdata: Cannot listen socket. # : Success

Trying a different port:
[/opt/NetData/bin] # ./netdata -p 2020
16-03-30 19:45:58: ERROR: netdata: Cannot open file '/opt/NetData/etc/netdata/netdata.conf' (errno 2, No such file or directory)
16-03-30 19:45:58: ERROR: netdata: IPv6 socket() failed. (errno 97, Address family not supported by protocol)
Managed to open an IPv4 socket on port 2020.[/opt/NetData/bin] #

Indeed there's no conf file in that directory, but no idea about the IPvX errors...

Ah, it was probably already opened because I had already opened the web page before that.

If you can see how/when the conf file is created it'd be great :)

Ah, that's weird; reading the documentation I visited myNAS:9119/netdata.conf and it actually exists - somewhere! Here it is:

[EDIT] Ah darn, it's too big and gets rejected by the forum; let me know if you're interested in me uploading it somewhere!
