Here they are:
We're using many different Netapps, F520's, F630's, and F740's.
One trick which really helped to start things off was making sure you are running a current (or at least recent) OS on your netapps.
I'm running 6.1.2R2 for the ones which support it. The reason this is important is because I use SNMP to capture the data I want, and the MIBs from the newer version are much better/consistent.
For the ops, I read the trap file in /etc/mib/traps.dat that explains what each OID does, and then started extracting. To get CIFS/NFS ops chart, I created three data sources, one for cifs, one for nfs, and one for the total of the two. The first two are data source type COUNTER and data input type "Get SNMP Data", with values of hostname, the community string "public" (or yours if you have changed it), and finally the two OIDs for cifs and nfs data.
cifs oid: .1.3.6.1.4.1.789.1.7.3.1.1.1.0
nfs oid: .1.3.6.1.4.1.789.1.2.2.1.0
The third data set doesn't exist directly within the SNMP tree. So I created it by creating a new "Data Input Source". The way I chose to do it was by writing a little script that gets passed as many OIDs as you want, and an option of what to do with the data from those OIDs. Thus this script requires either access to the "snmpget" command (in unix) or use of Perl and the SNMP_Session module. I chose to be lazy and used snmpget.
Here's the script I wrote (I put it in the scripts dir):
Code: Select all
#!/usr/bin/perl -s
$cmd_snmpget = '/usr/local/bin/snmpget';
chomp(@data = qx($cmd_snmpget -O neEXbqfsStv @ARGV));
if ($debug) {
print "ARGS: @ARGV\n";
print map { "DATA: $_\n" } @data;
} elsif ($add) {
foreach $set (@data) {
$total += $set;
}
print $total;
} elsif ($subtract) {
# Assume only two data sets
print abs($data[0] - $data[1]);
}
exit(0);
community
data
ip
oids
options
Only the "data" field is marked "Update RRA".
The input string looks like this:
<path_cacti>/scripts/snmp.pl <options> <ip> <community> <oids>
The output string looks like this:
<data>
So then I just pass both OIDs to this script along with the option "-add" and this returns the aggregate sum. I put this into a data source called "ops_total", type COUNTER.
Finally, I graph them like this (the order is important to make the graph look right):
Code: Select all
Graph Item Data Source Name Graph Item Type Item Color Sequence Add
Item #1 arna01_ops_tot AREA 002A8F [Down], [Up] Remove
Item #2 arna01_ops_tot: Cur: GPRINT [Down], [Up] Remove
Item #3 arna01_ops_tot: Avg: GPRINT [Down], [Up] Remove
Item #4 arna01_ops_tot: Max:<HR> GPRINT [Down], [Up] Remove
Item #5 arna01_ops_nfs LINE2 CAF100 [Down], [Up] Remove
Item #6 arna01_ops_nfs: Cur: GPRINT [Down], [Up] Remove
Item #7 arna01_ops_nfs: Avg: GPRINT [Down], [Up] Remove
Item #8 arna01_ops_nfs: Max:<HR> GPRINT [Down], [Up] Remove
Item #9 arna01_ops_cifs LINE2 AAABA1 [Down], [Up] Remove
Item #10 arna01_ops_cifs: Cur: GPRINT [Down], [Up] Remove
Item #11 arna01_ops_cifs: Avg: GPRINT [Down], [Up] Remove
Item #12 arna01_ops_cifs: Max:<HR> GPRINT [Down], [Up] Remove
I'm working with my employer to externalize the charts we run so that others can see them if they want, but we'll see if they will let me or not.
