Introducing gdash - GlusterFS Dashboard - Aravinda Vishwanathapura

UPDATE: Added --gluster option to specify the path to gluster. By default it looks for /usr/sbin/gluster, If you installed GlusterFS using source install then use sudo gdash --gluster /usr/local/sbin/gluster. (Those who already installed gdash, can run sudo pip install -U gdash to upgrade.)

gdash is a super-young project, which shows GlusterFS volume information about local, remote clusters. This app is based on GlusterFS’s capability of executing gluster volume info and gluster volume status commands for a remote server using --remote-host option.

If you can run gluster volume info --remote-host=<HOST_NAME>, then you can monitor that cluster using gdash. Make sure you allow to access glusterd port(24007) for the machine where you will run gdash.

To install,

    sudo pip install gdash

    sudo easy_install gdash

gdash is created using Python Flask and ember (I used ember-cli).

Usage

Use case 1 - Local Volumes

Just run sudo gdash, gdash starts running in port 8080. visit http://localhost:8080 to view GlusterFS volumes of local machine.

Use case 2 - Remote Volumes

Run sudo gdash --host 192.168.1.6, visit http://localhost:8080 to view GlusterFS volume information of remote host. Dashboard shows all the volumes which are part of that remote host.

Use case 3 - Multiple clusters

Create a clusters.conf file as example shown below, specify at least one host from each cluster.

[clusters]
cluster1 = host1, host2, host3
cluster2 = host4, host5, host6

Run gdash using,

sudo gdash --clusters ~/clusters.conf

Use case 4 - Multiple teams

If two teams monitoring two clusters and if you don’t want to share the other cluster details then, just run below commands in two terminals and give respective URL to each team. Other solution is create two seperate config files and run it separately for different ports.

# Team 1, who monitors cluster1 http://localhost:8001
sudo gdash -p 8001 --clusters ~/clusters.conf --limit-cluster cluster1

# Team 2, who monitors cluster2 http://localhost:8002
sudo gdash -p 8002 --clusters ~/clusters.conf --limit-cluster cluster2

Available Options

usage: gdash [-h] [--port PORT] [--cache CACHE] [--debug] [--host HOST]
             [--clusters CLUSTERS] [--limit-cluster LIMIT_CLUSTER]
