ID: 8076 Title: New option cmk --rrd-convert for convertig existing RRDs Component: config Level: 2 Class: New feature Version: 1.2.5i6 This new commanline option for the <tt>cmk</tt> tool will change exising RRD databases to match the configuration that is done via the WATO rulesets <i>Configuration of RRD databases of hosts</i> and <i>Configuration of RRD databases of services</i>. Otherwise changes in these rules applied only on new RRDs. You can restrict the conversion to one or several hosts: C+: OM:cmk -v --convert-rrds myhost1 myhost2 myhost1: HOST - rta....uptodate - pl....uptodate - rtmax....uptodate - rtmin....uptodate Postfix Queue - length....uptodate - size....uptodate CPU utilization - user....converted, 376 KB -> 40 KB - system....converted, 376 KB -> 40 KB - wait....converted, 376 KB -> 40 KB [...] C-: If you do not specify any hostname, then <b>all</b> RRDs will be converted. <b>Note:</b> this new option uses a completely new feature of the RRDTool, which has been sponsored by Mathias Kettner: RRDTool can now change the internal structure of RRDs on-the-fly. That way it is now for example possible to change the range of time or precision that data is being kept. <b>Note 2:</b> this feature uses an <b>experimental</b> version of RRDTool. Please make a backup of your RRDs before trying this out.
