Look this server I thought: Look this configuration I assembled. 2x XEON CPUs (single core). 8GB RAM 4x 73GB SCSI HDs (RAID10) Red Hat MRTG Routers2 CA eHealth RRDtool EMC SAN (I forgot, We Can use this storage) From: mrtg <[email protected]> on behalf of thomaz portella <[email protected]>
I am reading the necessity of using RRDtool together with mrtg. Yes. Rrdtool scales much greater than rateup. Which benefits will I have using it or not ? Greater granularity (up to millisecond precision if you were to poll that often) as opposed to fixed at 5 minute polling cycle. Support for negative numbers (for example, temperature sensors or dB meters) Faster update times - just updating a database that is designed to consolidate daily/weekly/monthly/yearly views rather than fiddling with flat files that take a long time to parse and rewrite. Less up-front processing. Rateup creates a graph on every polling cycle. Rrdtool just updates the data and lets you create the graphs at time of view, leading to much lower cpu utilization. More flexible graphs - rrdtool gives you almost limitless formatting capabilities and combined metrics, while rateup just creates one style of graph. I need an external database or could be embedded ? Not for rateup. You may want one if you are tracking 100’s of switches. Large sites generally set up mrtg configs for each switch as a separate file, and then include them all from a master mrtg.cfg file that just contains include statements from all of the switches. For example, I have about 700 devices, all with unique snmp credentials. I have a database that lists the credentials, as well as which template should be applied to each device. I have a script that will check to see which devices are reachable, create a mrtg.cfg file with all of those config files included, and also put together a script to run mkconfig for a subset of the devices that are being managed.
