Sidekiq middleware that writes job lifecycle events as points to an InfluxDB database.
Add this gem to your application's Gemfile
:
bundle add sidekiq-influxdb
Sidekiq middleware description:
https://github.com/mperham/sidekiq/wiki/Middleware
InfluxDB client description:
https://github.com/influxdata/influxdb-ruby/blob/master/README.md
Add included middleware to your application's Sidekiq middleware stack:
# config/initializers/sidekiq.rb
require "sidekiq/influxdb/server_middleware"
Sidekiq.configure_server do |config|
config.server_middleware do |chain|
chain.add Sidekiq::InfluxDB::ServerMiddleware,
influxdb_client: InfluxDB::Client.new(options), # REQUIRED
series_name: 'sidekiq_jobs', # optional, default shown
retention_policy: nil, # optional, default nil
start_events: true # optional, default true
end
end
When you deploy this code, you will start getting the following series in your InfluxDB database:
> select * from sidekiq_jobs
name: sidekiq_jobs
time class creation_time error event jid queue total waited worked

Tags (repetitive, indexed data — for filtering and grouping by):
time
— Standard InfluxDB timestamp. Precision of the supplied client is respected. Onlys
,ms
, andu
precisions are supported.queue
— Queue name.class
— Job class name.event
— What happened to the job at the specifiedtime
:start
,finish
, orerror
. If you initialize the middleware withstart_events: false
, there will be nostart
events.error
— Ifevent=error
, this tag contains the exception class name.
Values (unique, non-indexed data — for aggregation):
jid
— Unique job ID.creation_time
— Job creation time.
Values calculated by this gem (in seconds):
waited
— How long the job waited in thequeue
until Sidekiq got around to starting it.worked
— How long it took to perform the job from start to finish or to an exception.total
— How much time passed from job creation to finish. How long it took to do the job, in total.
This schema allows querying various job metrics effectively.
For example, how many reports have been generated in the last day:
SELECT COUNT(jid) FROM sidekiq_jobs WHERE class = 'ReportGeneration' AND time > now() - 1d
How many different jobs were executed with errors in the last day:
SELECT COUNT(jid) FROM sidekiq_jobs WHERE event = 'error' AND time > now() - 1d GROUP BY class
Et cetera.
After checking out the repo, run bin/setup
to install dependencies. You can also run bin/console
for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install
. To release a new version, update the version number in version.rb
, and then run bundle exec rake release
, which will create a git tag for the version, push git commits and tags, and push the .gem
file to rubygems.org.
