🔗 utilization report
The utilization report details statistics about the amount and type of traffic through the Squid.
First shown are the statistics for several time periods, as detailed in the section headers. These range from previous 5 minutes up to several days. They show the KB/second throughput rates for each traffic type.
Finally the total statistics since Squid was started. This is an all time report with absolute counts in bytes, KB, or seconds.
🔗 What is server.other?
Other is a default category to track objects which don’t fall into one of the defined categories.
🔗 What is the Max/Current/Min KB?
These refer to the size all the objects of this type have grown to/currently are/shrunk to.
🔗 What is the I/O section about?
These are histograms on the number of bytes read from the network per read(2) call. Somewhat useful for determining maximum buffer sizes.
