 +===== ROHC statistics =====
  
 +**For versions >= 1.7.0 of the library only**
 +
 +The ROHC stats application makes it easy to gather some (de)compression statistics from one network flow (in PCAP format). The tool outputs statistics in CSV format with the following tab-separated fields:
 +  * keyword '​STAT'​
 +  * packet number
 +  * context mode (numeric ID)
 +  * context mode (string, no whitespace)
 +  * context state (numeric ID)
 +  * context state (string, no whitespace)
 +  * packet type (numeric ID)
 +  * packet type (string, no whitespace)
 +  * uncompressed packet size (bytes)
 +  * uncompressed header size (bytes)
 +  * compressed packet size (bytes)
 +  * compressed header size (bytes)
 +
 +Once the ROHC library and tools are installed, get some more help with:<​code>​
 + $ man rohc_stats</​code>​
 +or:<​code>​
 + $ rohc_stats --help</​code>​
 +
 +A helper shell script is also provided to generate an HTML page with pretty graphs on it:<​code>​
 + $ ./​rohc_stats.sh network_flow.pcap ./​network_flow_stats/​
 + $ firefox ./​network_flow_stats/​index.html</​code>​
 +
 +
 +Additional informations:​
 +  * Use for testing/​debug only, it was not designed for production at all.
 +  * Developed in the [[https://​github.com/​didier-barvaux/​rohc/​tree/​master/​app/​stats|app/​stats/​]] sub-directory of the library source code.
 +  * License: same as ROHC library
