Page description:

- Site name
- hovering over the site name provides a tooltip with links to MRTG monitoring pages of site's squids
- history
- link history of states in form of csv file (for easier searching)
- f/r (fetch/request ratio)
- Values of fetch and requests are taken from weekly average in 30 min bins of the MRTG.
- The value is either f/r value of a single squid or, if there are more squids at the site, it is maximum of f/r values.
- If there is less than 500 request on average, the ratio is set to 0 to avoid false alarms caused by inactive squids
- Background color can change depending on the f/r value:
- If the f/r value is "high", it means the squid has problem with caching and many requests are read from database instead of squid's cache.
