Boatswain Public BETA-I released

Leave a comment

Finally…

It has been almost 3 years (Early August 2015) since we came up with the idea of Boatswain and today our first public beta is…

Why it takes so long?

🐢

Time to market is important.

🙈

I have heard many sincere advice in the past two years from my friends and I would like to thank everyone of them who has spent their time on Boatswain. And most importantly, I would like to express my deep appreciation to Steven Yeung, another Founder of Boatswain. He is the core “Engineer” of the project and without him it definitely needs to take three more years to deliver this release.

I don’t want to make a 30 mins article although i got a lot of words which i want to say. We hope to keep working on Boatswain but we need your help to make it better and if you have any question, suggestion or any comment just drop us a message. Your feedback is most welcome and highly appreciated. Thanks! 🙏

collectd is a statistics gathering tools which helps system admin to analysis the system conditions. It includes both server and client implementations. The collectd client send metrics to the collectd server.

 

I installed the collectd on a CentOS 7 machine and try to send the metrics to a Graphite instance. But no matter how i changed the setup, the Graphite couldn’t receive any data. Finally, i realized that it is blocked by the SELinux policy.

Compared to Graphite, installing StatsD server is just a piece of cake.

1. Install Node.js. For better management on Node.js, you could consider using nvm.

 

2. Checkout the StatsD project on GitHub.

git clone https://github.com/etsy/statsd.git

 

3. Copy the exampleConfig.js and name it to whatever you like and edit it as follow.
ex. statsdConfig.js.

{
  graphitePort: 2003
, graphiteHost: "<graphite host>"
, port: 8125
, backends: [ "./backends/graphite", "./backends/console" ] // console is for debug
, debug: true // For debug
, graphite: { legacyNamespace: false } // Better group all collected metrics under stats
}

Monit is a opensource monitoring tool on Unix system. The simplest use case would be restarting your service if there is failure.
