Cacti spine not updating rrd
In addition it allows the CPU load to be reduced by Caching commonly viewed graphs.In addition, it allows the RRDfile updates to be handled by an update server, thus allowing the Cacti administrator to restrict web site accounts from having to grant read/write access to the RRDfiles.Multiple Log File Destinations including syslog (Unix), Event Log (Windows), and a standard log file.Syslog/Eventlog support makes it easy to get notified when critical poller events occur.
In this case, when sizing the poller_output_boost table, you take the output column width and add 34 bytes per record.
A Revamped Poller Architecture which supports variable log levels, multiple log destinations, auto data query recache detection, and host availability sensing.
Cacti is now capable of spawning multiple simultaneous poller threads to increase the efficiency of the polling process.
Let's say, for example, that your poller cache contains 200k rows, and the maximum length of any row is 20 bytes, about the size of a 64bit counter.
If you are running scripts, ones that return very long results, like the My SQL statistics plugin, you should consider carefully the next step.
