All,
We are in the process of going from Hobbit 4.2.0 to Xymon 4.3.0-0.beta2.
We originally set up the timeframes for the rrd files as such on the new Xymon server.
/* Check if the default record exists */
if (rbtFind(rrddeftree, "") == rbtEnd(rrddeftree)) {
/* Create the default record */
newrec = (rrddeftree_t *)malloc(sizeof(rrddeftree_t));
newrec->key = strdup("");
newrec->defs = (char **)malloc(4 * sizeof(char *));;
newrec->defs[0] = strdup("RRA:AVERAGE:0.5:1:157824");
newrec->defs[1] = strdup("RRA:AVERAGE:0.5:6:157824");
newrec->defs[2] = strdup("RRA:AVERAGE:0.5:24:157824");
newrec->defs[3] = strdup("RRA:AVERAGE:0.5:288:157824");
newrec->count = 4;
rbtInsert(rrddeftree, newrec->key, newrec);The belief was that we would be able to keep 5 minute increments of data out to 576 days. Now because of the amount of space required, that have asked to keep the 576 day average to 30 minutes instead of the 5 minutes and keep the 2, 12 and 48 days at 5 minutes. As I will not have time to make sure that long of time is correct, so I need some other eyes to tell me if my calculations are correct.
I am planning on taking newrec->defs[3] = strdup("RRA:AVERAGE:0.5:288:157824"); and changing 157824 to 82944.
Am I correct in my calculation for the 576 day average for 30 minutes or am I totally off base?
We are keeping the original Hobbit server for historical review and I don't have to worry about converting any rrd files. And because we are in test, I can simple blow away the new rrd files on Xymon.
All comments will be appreciated!
Thank you,
Tom
