Technical info / Security

This document contains more technical information about how the CoScale agent works, security measures and network requirements.


The CoScale agent is a downloadable software component for different Operating Systems and Software. CoScale analyzes log files or connects to the Software’s management interface. For example, in the case of Apache web server, the access.log file is parsed and the default Apache server-status page is fetched and parsed for getting general info. CoScale does not interfere with your application stack, CoScale does not do binary instrumentation or we do not dynamically generate and inject code into other processes.

Data storage

CoScale is using dedicated servers. All of our production servers are in a data center in Roubaix, France (Certifications). CoScale uses standard best practices to maintain a firewall for our servers and to protect our servers from unauthorized login. All data is stored in a cluster of PostgreSQL and Cassandra databases. Metric data is not stored encrypted. CoScale data is backed up nightly.

Security & Firewall

By default, all CoScale agents communicate with the CoScale platform over a secured SSL connection, using the default port 443. The agent communicates with one host, (,, and CoScale only requires your firewall to allow outgoing connections to on TCP port 443. No incoming connections are required.

All installed agent plugins are digitally signed by CoScale. This signature is verified when installing or updating plugins.

The agent has a built-in access token (GUID) to authenticate with the CoScale platform. This token can always be revoked when necessary.
