I'd like to graph ccache statistics but I'm unsure if rrdtool would be the right way to do this. A sample (snipped) output from it is below:
desktop david # ccache -s cache hit 951 cache miss 377 files in cache 754 cache size 5.1 Mbytes As these figures aren't going to change much in 5 minutes, I feel it would make sense to log the numbers every 30 minutes for a week, then every day for a year. I have other graphs that seem to work well with these time periods. However, the numbers from ccache aren't a rate or average, they're a total of how many times the cache has been hit since the counters were last reset. When reading them, for example every 30 minutes, I would reset the hit and miss. I already have other graphs for partition space usage so I am fairly sure "cache size" would be graphed fine, I am just unsure about the hit and miss and total files. Does it make sense to graph these figures using rrdtool? Should I be using GAUGE or is it an ABSOLUTE? I think it would be ABSOLUTE for hit and miss (as they are reset upon reading) and GAUGE for the total files and cache size. Which consolidation function should I use for the RRA?
