Hi Stanislav, If you look at the directory run/monitoring under the install path on the master server, you will see these files:
rs_map.txt rs_stats.txt table_stats.txt rs1_stats_v0.rrd rs2_stats_v0.rrd .... rsN_stats_v0.rrd The file rs_map.txt contains a mapping from range server id (ie rs1, rs2 etc) to ip address. The file rs_stats.txt contains stats for the last 1,5, 10 min time intervals for all rangeservers. The file table_stats.txt contains stats for the last 1,5, 10 min time intervals for all tables. The file rsi_stats_v0.rrd is an RRD file containing archived stats for the ith rangeserver (upto last 18 months) I believe. To see how to extract data from the RRD database you can look at the Monitoring UI code (src/rb/Monitoring) or take a look at the RRDTool documentaion<http://oss.oetiker.ch/rrdtool/doc/index.en.html>. By default the system updates statistics every 30s which can be controlled via the config "Hypertable.Master.StatsGather.Interval". You can use rrdtool info to examine the contents of the rrd file, for example to list all the stats stored in it: *rrdtool info rs1_stats_v0.rrd |grep "ds.*type"* -Sanjit On Fri, Sep 10, 2010 at 12:40 AM, Stanislav Yudin <[email protected]> wrote: > Congratulations on this milestone! > This release includes monitoring UI, but what about Monitoring APIs?
