collectd-transmission v2.0

A python plugin for collectd to get stats from a runnning transmission server.

Introduction

A python plugin for integrating collectd and transmission. With this installed, collectd will be querying transmission for the following:

Per session and cumulative:

• downloadedBytes

• uploadedBytes

• filesAdded

• secondsActive

General:

• activeTorrentCount

• blocklist_size

• downloadSpeed

• uploadSpeed

• pausedTorrentCount

• torrentCount

and creating the relevant RRD files (or pushing to graphite or whatever you have collectd doing)

Some of these metrics are per session, some session cumulative, some are session independent. Their type ‘current’, ‘cumulative’, ‘general’ is set in the name of the metric

Compatibility

Developed and tested on Debian Wheezy system.

That means:

• collectd 5.1

• transmissionrpc 0.8

But testing has also been conducted on Debian Jessie systems. Which means:

• collectd 5.4

• transmissionrpc 0.11

It is expected Debian Jessie will be the main playground soon

Feel free to submit PRs for other systems support

How to install

Prerequisites

Those are collectd and transmission

I assume a Debian system here, amend accordingly for your system

If you have not already installed transmision, install it:

apt-get install transmission-daemon

The above install the daemon cause a headless box is assumed. It should probably work with a non headless box as well and a normal transmission installation but this has not been tested.

Install the python transmission binding

apt-get install python-transmissionrpc

Install collectd.

apt-get install collectd

Install collectd_transmission

There are two ways to achieve this for now

Use the python package

pip install collectd_transmission

Do it manually

Clone the repo, copy the module directory somewhere in your fileystem

Configure

Insert the following in your collectd.conf:

<Plugin python>
    ModulePath "/path/to/module/dir" # Not needed if installed via pip or package
    LogTraces false
    Interactive false
    Import "collectd_transmission"
    <Module collectd_transmission>
        username "myuser" # Required
        password "mypass" # Required
        address "http://localhost:9091/transmission/rpc" # Optional, defaults to "http://localhost:9091/transmission/rpc"
        timeout "5" # Optional, defaults to 5
    </Module>
</Plugin>

modified accordingly to your needs. Restart collectd and you are done.

sudo service collectd restart

There should be rrds for transmission under collectd’s data directory. Most probably that is /var/lib/collectd/rrd/<hostname>/transmission/

How to display your data

Well if you got collectd, you probably already have a way of displaying your data anyway. If you don’t there are various frontends available at:
