I tried several manuals which is available online but I always end up the same problem.My Graphs is not showing anything and it's only showing a broken link icon.Normally this is 300 seconds (5 minutes) so all data is stored in a 5 minute interval.This doesn’t mean you only can add data every 5 minutes though.
Even though many consider RRD as a library to create graphs, it is actually more than that: it’s a complete system to store aggregated data in a very efficient way. It is a database for collecting all kinds of data against time.Thanks everyone for giving this thread a reply and taking time to read it. Remove text/html since it's redundant, and add a few others. Reduces load time on slow connections to about 1/4th of what it is without gzip on json. I touched them last a while back but I only managed to make them suck slightly less. The "end" of the graph (right side) always seems to fall to 0, it's more noticeable on the 1 hour graph choice.The “round robin” stands for the fact that only a certain amount of “data points” can be stored.When we reach the end of the database, it will wrap back to the begin again.No more additional login into a second application, no more manual search and mapping of devices between Nagios and Cacti.We still retain Cacti, but it lost most of its importance.I did try running the manually and made sure my rra folder is writable but I am always getting this error.RRDTool Command: /usr/bin/rrdtool graph - \ --imgformat=PNG \ --start=-86400 \ --end=-300 \ --title='Localhost - Load Average' \ --rigid \ --base=1000 \ --height=120 \ --width=500 \ --alt-autoscale-max \ --lower-limit=0 \ --units-exponent='0' \ --vertical-label='processes in the run queue' \ --slope-mode \ --font TITLE:10: \ --font AXIS:7: \ --font LEGEND:8: \ --font UNIT:7: \ DEF:a="/var/www/html/rra/localhost_load_1min_5.rrd":load_1min: AVERAGE \ DEF:b="/var/www/html/rra/localhost_load_1min_5.rrd":load_5min: AVERAGE \ DEF:c="/var/www/html/rra/localhost_load_1min_5.rrd":load_15min: AVERAGE \ CDEF:cdefg=TIME,1348538002, GT,a,a, UN,0,a, IF, IF, TIME,1348538002, GT,b,b, UN,0,b, IF, IF, TIME,1348538002, GT,c,c, UN,0,c, IF, IF, , \ AREA:a#EACC00FF:"1 Minute Average" \ GPRINT:a: LAST:" Current\:%8.2lf\n" \ AREA:b#EA8F00FF:"5 Minute Average": STACK \ GPRINT:b: LAST:" Current\:%8.2lf\n" \ AREA:c#FF0000FF:"15 Minute Average": STACK \ GPRINT:c: LAST:"Current\:%8.2lf\n" \ LINE1:cdefg#000000FF:"" RRDTool Says: ERROR: opening '/var/www/html/rra/localhost_load_1min_5.rrd': No such file or directory Most of the forums I found on the net that shares the same issue doesn't really have solutions yet, so I am really hoping someone from WHT can help with this. OK, when you installed cacti, did you read and follow all the instructions?This means that RRD database files will never grow in size.Every RRD works with a “step rate”, which tells us how far the data points are located from each other.For us, Nagiosgraph is the most important extension to our monitoring system.Before Nagiosgraph, we had been relying entirely on Cacti for performance monitoring.At the time of implementation in 2008, the Nagiosgraph package was not well maintained and contained a serious bug (Nagiosgraph v0.9.1).
