What’s new in Server Density – August 2013

By David Mytton,
CEO & Founder of Server Density.

Published on the 30th August, 2013.

Each month we’ll round up all the feature changes and improvements we made this month to our server and website monitoring product, Server Density.

TCP port checks

In addition to our HTTP(S) website checks, you can now create TCP checks on any port. You can send a data string as part of the check, configure alerts based on the status (up, down or slow), monitor response time (and set alerts on it) and create alerts based on the response. And of course you can choose which of our locations you want to execute the checks from.

Automatic agent installation shell script

The installer script for the agent has been extended to take an API token instead of an agent key so that it will automatically register the server against our API, requesting an agent key in the process. This means you can just run the script as part of your provisioning process and it will automatically install the agent and register it, starting monitoring automatically. You can also specify a group name so the new device will inherit any group level alerts.

Instructions for use are available on our support site.

API documentation available

The initial API docs are available for our read/write API which allows you to pull out details of all your servers and service checks, as well as add new ones.

Improved alerting options for service checks

To help avoid false positives, you can now choose how many locations are necessary to trigger an alert. Previously alerts would be sent if just 1 location saw a service as down but this can be too sensitive. You can now select how many locations are required and the alert notifications include the up/down locations so you can see where the problems lie.

Choosing locations for Server Density alerts

Improved timezone handling

Timezone selection from your user profile is now fully reflected across the entire web UI and will automatically be set to your current timezone the first time you log into the app.

Improved alert recipient selection UI

The recipient selection UI has been redesigned to make it clearer which users and notification types are enabled.

New monitoring locations

Our website monitoring allows you to choose which location(s) you want us to conduct checks from. We have now added new locations in Chile, France, Italy and Hong Kong. You can select any combination to match where your visitors are located.

All locations + IPs are listed in our docs. Let us know if you want monitoring somewhere else.

What’s next?

Our redesigned graphing is nearing completion and we’ll then be moving on to user management, expanded API docs and global alert history.

What about v1 migrations?

We have started inviting users to migrate to v2, and will shortly be opening this process more widely. We are gradually allowing migrations to allow us to fix any issues and deal with feedback from existing users.
