Greetings all I'm new to rrdtools. I'm actually still evaluating it as as tool for storing monitoring metrics. After reading the documentation and several discussions in this list and also in other forums I'm still confused about a couple of things. 1. How are subsecond timestamt reported? In several places it is mentioned the existence of these timestamps, but can't find any example of how to specify it in the update command, except when using "N" as timestamp.
2. Supposing subsecond timestamps are supported by rrdtools, are they also supported by rrdcached? 3. Finally, is there any patch to add SUM function for totalizing a metric over a period. This is a very important requirement as we need to count the total number of certain events for minute, hour and day. I'm aware of the approach of using the average and multiplying by the reporting period, but this will lead to a approximated value. Even when I understand the concerns about it not working properly in all situations, I think is a very common requirement. Simply can't believe nobody has done this ever, unless I'm completely wrong about the need of such function. many thanks in advance -- Pablo Chacin R&D Engineer SenseFields SL Tlf (+34) 93 418 05 85 Baixada de Gomis 1, 08023 Barcelona (Spain) http://www.sensefields.com/ _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
