RRDTool: A Round Robin Database for Network Monitoring

RRDtool is a circular database that stores time series data. RRD tool assumes time-variable data inintervals of certain length. An interval named as step, and specifiedupon creation an file which cannot be changed afterward. Because datamay not always come at just the right time, will automaticallyinterpolate any submitted This done to fit its internal timestamps. Ifwe compare linear databases with then we can say non-linearlike queue. Usually, in aRound-Robin Database (RRD), time-series like network bandwidth, memoryusage, CPU load are stored. The stored non-linear way so thatthe system storage footprint remains constant over time. avoidsresource-expensive purge jobs reduce complexity. MySQL does NOT provideany such kind engine. has also ability create andfeed this database. data; makes it back-end tool. command set allows graphs front-end toolas well. Other store graphs. combinedwith NET-SNMP collect using scripts generate beautifulreal-time used for monitoring computer networks.
