VARA Log collection

Participating TPRFN Hub Stations are encouraged to send their VARA log messages to a central server using syslog. Every fifteen minutes, a static page is generated to show the log entries (VARA syslog button above). Logs are archived on the server, but only the current day is visible on the website.

Turning VARA Logs into Network Graphs

Once every fifteen minutes, the VARA logs are parsed into (currently) 2 different network graphs, which are accessible using the buttons above. These network graphs do not show geographically where the Hub Stations and polling stations are - they do show the Hub Stations and the polling stations. Lines between polling stations and Hub Stations indicate either if a Hub Station heard a polling station or if a polling station connected to a Hub Station.

This is done using a series of scripts written in bash, awk, sed and perl. Once we have the list of Hub Stations and polling stations, and the connetions between them, the network graphs are generated.

How do I get my Hub Station in here?

These network graphs and metrics are only intended for TPRFN Hub Stations - if you are a TPRFN Hub Station and would like to be included, please contact K1AJD (callsign @ k1ajd.net) - here are the requirements:

  • Using a registered version VARA that supports syslog

How do I set this up in my area?

Good question! Heather has placed a set of instructions over at github.com,otherwise feel free to email K1AJD.
