Rrdupdate not updating

The problem/bug is actually archived here, however this post didn't help.

I can snmpget the value, e.g filename = "powerbseipv6testrouter_cisco_memfree_40.rrd" rrd_version = "0003" step = 300 last_update = 1321867894 ds[cisco_memfree]= "GAUGE" ds[cisco_memfree].minimal_heartbeat = 600 ds[cisco_memfree]= 0.0000000000e 00 ds[cisco_memfree]= 1.0000000000e 12 ds[cisco_memfree].last_ds = "UNKN" ds[cisco_memfree].value = 0.0000000000e 00 ds[cisco_memfree].unknown_sec = 94 rra[0]= "AVERAGE" rra[0]= 600 rra[0].pdp_per_row = 1 rra[0]= 5.0000000000e-01 rra[0].cdp_prep[0].value = Na N rra[0].cdp_prep[0].unknown_datapoints = 0 rra[1]= "AVERAGE" rra[1]= 700 rra[1].pdp_per_row = 6 rra[1]= 5.0000000000e-01 rra[1].cdp_prep[0].value = Na N rra[1].cdp_prep[0].unknown_datapoints = 0 rra[2]= "AVERAGE" rra[2]= 775 rra[2].pdp_per_row = 24 rra[2]= 5.0000000000e-01 rra[2].cdp_prep[0].value = Na N rra[2].cdp_prep[0].unknown_datapoints = 18 rra[3]= "AVERAGE" rra[3]= 797 rra[3].pdp_per_row = 288 rra[3]= 5.0000000000e-01 rra[3].cdp_prep[0].value = Na N rra[3].cdp_prep[0].unknown_datapoints = 114 rra[4]= "MAX" rra[4]= 600 rra[4].pdp_per_row = 1 rra[4]= 5.0000000000e-01 rra[4].cdp_prep[0].value = Na N rra[4].cdp_prep[0].unknown_datapoints = 0 rra[5]= "MAX" rra[5]= 700 rra[5].pdp_per_row = 6 rra[5]= 5.0000000000e-01 rra[5].cdp_prep[0].value = Na N rra[5].cdp_prep[0].unknown_datapoints = 0 rra[6]= "MAX" rra[6]= 775 rra[6].pdp_per_row = 24 rra[6]= 5.0000000000e-01 rra[6].cdp_prep[0].value = Na N rra[6].cdp_prep[0].unknown_datapoints = 18 rra[7]= "MAX" rra[7]= 797 rra[7].pdp_per_row = 288 rra[7]= 5.0000000000e-01 rra[7].cdp_prep[0].value = Na N rra[7].cdp_prep[0].unknown_datapoints = 114 Aside from upgrading to the latest 0.8.8, have you confirmed that you (or whatever is attempting to store the rrd information in the file) can?

For our example, this monitoring server's IP is 198.211.117.251.

All the future config snippets will reference this IP, so make sure to change it to your own value.

They are used to plot all kind of data against time in a very easy way which is why they are used a lot in all kind of applications.

RRDtool (acronym for round-robin database tool) correlates time-series data like network bandwidth, temperatures, CPU load or any other data type.

We highly suggest using RRDtool v1.2.x which require very few dependancies compared to v1.4.x.

You may not be familiar with the term RRD graph, but if I show you one, you probably recognize them instantaneously.

The first set of commands creates and updates the data file, while second one plots this data into a PNG file that will be saved into Apache's Document Root path.

Save this file as /root/and make sure you do not have any spaces after '\' since this is all a single line that was broken into multiple: #!
