When you issue a write to a Netapp filer, it is journalized in NVRAM and a ack is sent back. so the write latency is basicaly 2 x network transfert time + NVRAM latency, which could be in the microsecond range. NVRAM is flushed to disk every 10 seconds or when it is half full. Write latency typicall...

You must use a counter instead of a gauge in your data template.

Memory consumption of the editor seems to have grown a little bit since 0.95b. I hit the famous "Allowed memory size of 8388608 bytes exhausted (tried to allocate 138 bytes)" error in Apache when editing the most complex map I have (about 30 nodes and 35 links). I thought I already increas...

wmic linux binaries are provided, if they don't work in SLES10 for whatever reason, you can compile them yourself as wmic is an open source project.

The patch you tried is to be used against cacti 0.8.7d, that's why you see a lot of failed hunk. You will need to restore the original files in order to have cacti work again, and apply a patch for 0.8.7b (try with --dry-run to see if everything goes well). On a side note, on my Debian test server, ...

use SNMP v2 and 64 bits counters.

which version of rrdtool are you using ?
1.2.26 disable read-ahead caching, which might help in your situation.
1.3 has a feature called "fadvise", which is smarter.

I wrote some time ago a script which do the same, but with no verification whatsoever. Its purpose was to ease automatic installation of my servers.

I would love to see this kind of scripts added to Cacti

the GPRINT type of your legend items in your graph template need to be set to "Exact Number". I recommand keeping the "average" item to "Normal". If you don't have the "Exact Number" GPRINT preset, create a new one and enter "%8.0lf" without the quot...

you need to poll SNMP 64 bits counters and use SNMP v2 for your device.

When you create a graph using the SNMP - Interface Statistics data query, select "in/out bits (64-bits counters)" in the drop down menu.

you must poll the device using SNMP v2c (or v3) and use 64 bit counters.

that's quite high value
try Poller Processess = 2 * number of cpu
threads per Process = doesn't matter if you don't use cactid (spine), but 2-4 are quite common.

95th Percentile should be calculated on data which are not consolidated.
If you want 95th percentile on the monthly graph, your 5 minute RRA should contain more than 31 days.
