====== TLS Metrics ======

This article helps with providing the steps for installing the TLS Metrics app in Trisul Network Analytics.

**
To provide Protocol information about the data encrypted with the help of several Metrics.

The App provides the following,

**Metrics:**
  * TLS Versions : Traffic and flow using each TLS version in your network.
  * TLS Cert Public Key Algorithms : Certficate metrics, meters type of public key algorithm (RSA/ECC). If using ECC, the name of the curve, or "explicit-parameters".
  * TLS Cert Signature Algorithms : Certificate metrics, meters,type of signature algorithms.

**Edges:**
  * Edges between Signature Algorithm & Common name.
  * Edges between Public Key Algorithm & Common name.
  * Edges between TLS & Flow Tuples.

===== Installation =====

  - You can install the app by logging on as Admin and selecting //Web Admin > Manage > Apps > TLS Metrics Pack.//
  - Restart the Probes after installing the app.

===== Viewing Data =====

For TLS Versions,
  * Select //Retro > Retro Counters//.
  * Select the 'TLS Version' counter group.
  * You can also view the edges by exploring the entries for further analysis.
