A community package is now available for the Grafana application.
Official description:
Grafana provides a powerful and elegant way to create, explore, and share dashboards and data with your team and the world.
Grafana is most commonly used for visualizing time series data for Internet infrastructure and application analytics but many use it in other domains including industrial sensors, home automation, weather, and process control.
Important: This package is designed to be fed by the NetData application for monitoring measures, so please make sure the YunoHost NetData package is installed before installing it!
NetData only collects, displays and sets alarms based on data from the last hour; this packages allows to archive every metrics and put up statistics and dashboards on the long term.
Important at first login:
you have to go the Grafana Menu (Grafana icon), select your account menu and select Switch to Main Org.
you can now access the default NetData dashboard via the Home menu
Don’t hesitate to create new dashboards: the default dashboard contains metrics from NetData, but only generic ones that are generated on every machine. NetData dynamically detects services and applications (e.g.redis, nginx, etc.) and enriches its dashboard and generated metrics. Many NetData metrics don’t appear in the provided default Grafana dashboard!
Warning: The default dashboard may be updated in a further release of this package, so please make sure you create your own dashboards!
Also, don’t hesitate to propose your dashboards to be integrated into this package
Package description:
installs InfluxDB as time series database
if the NetData package is installed, configures NetData to feed InfluxDB every minute
installs Grafana as dashboard server
creates a Grafana Data Source to fetch data from InfluxDB (and hence NetData!)
creates a default dashboard to plot some data from NetData (doesn’t cover every metric, can be greatly enhanced!)
Configuration files are in /etc because it installs official packages for Debian. NetData is compiled during installation, so I let the default parameters to install to a separate location in /opt.
I will have a look at your issues, thanks for that!
Really great idea. It could be great to use the data from glance because it is already installed on yunohost and glance could be used with influxdb. It’s juste an other idea to impove the app.
1: Cannot login after logout - Organization creation doesn’t play well with LDAP integration. Organization creation has been disabled by default for standard users; please do not create organizations via you administrator account!
2: Grafana administrator - Installation now asks for an administrator to give privileged rights
In order to get administrator rights, and provided the package was released yesterday, it is advised to uninstall and reinstall.
Using Glances integration with InfluxDB is a good idea!
The problem is that we need to modify a system file (/etc/glances/glances.conf), which we try to avoid in packages.
Maybe I could at least add the possibility to the README and integrate the default Glances dashboard… ?
Do you know if there is any way to reduce the memory consumption of Inbound.db ?
It’s currently taking more than 450MB of RAM (it increases progressively), and as I’m on a raspberry pi, it often needs to swap when I launch a memory hungry task.
Having nice metrics of my system is a good thing, but if that’s the actual cost of it I can’t really let my raspberry swap 90% of the time.
Hi,
I totally understand your frustration.
I can’t reproduce your problems right now, but my servers were rebooted a couple of days ago because of the security update. Yet I didn’t experience such problems the weeks before. I’ll see how it gets in the following days.
Anyway, there seems to be memory problems experienced by others in some situations. You could maybe try this configuration?
Unfortunately on my x86_64 or ARM servers, influxdb keeps a memory occupation between 120 and 140Mb after a couple of weeks, so I don’t know right now how to assist you…
If I stop influxdb and grafana services (+netdata), it’s enough to stop everything right ?
I’d like to try disabling both, to be sure the memory issue is not coming from elsewhere. It’s growing really slowly, but surely, and restarting those processes gave ~50MB of extra free memory, but I’m not sure it reduce the memory amount completely.
Yes, you have nothing more to do to disable Grafana package other than stopping influxdb and grafana-server services.
You can let the netdata service on; it will try to contact the backend server (influxdb) a few times, but will stop trying after a couple of failures.
Indeed, it was an not issue related to grafana. Solved now
I have another question: I use this command /opt/vc/bin/vcgencmd measure_temp to get the temperature of my Rasberry Pi. Im’ wondering if there is a way to include this data in grafana (so in netdata too I suppose).
Do you know if it’s possible ?
I would say it is possible to feed InfluxDB withy our values and then serve them to a custom dashboard in Grafana, though I haven’t done anything like this myself.
It could be great to use the data from glance because it is already installed on yunohost and glance could be used with influxdb. It’s juste an other idea to impove the app.
