Brocade Fibre Channel templates.

I changed to cactid - snmp walking works perfect.
Now the system produces no graphs and I can't find no hints in the logs at all.

There are not even rra files for the added hosts in rra dir.....

Hi,

I'm currently starting to use cacti to get some closer look at our SAN switches.
After installing the normal SuSE stuff (we are working with SuSE ...) Cacti
cacti-0.8.6h-36.2 is up and running. I've added a host (for testing) and also
both Brocades (SW 4100).
I can monitor fan and temp, but I see not a single fc port ...

Adding the data query for Brocade_ports shows this output.
So what's wrong with my setup ?
snmpwalk shows all values.

Thanks for your help !
Bye, Peer

Debug output is
+ Running data query [10].
+ Found type = '4 '[script query].
+ Found data query XML file at '/usr/share/cacti/resource/snmp_queries/brocade_interfaces.xml'
+ XML file parsed ok.

Hi,

I have no problems querying a Brocade 4100....community settings correct? I am using SNMP V2.....

for testing I have added you my modified template for the Brocade 4100

[b]Please be careful - nyx said that some Interface graph templates will be changed while importing my host template......sorry for the confusion...

But that is a general problem of cacti when you want to import host templates - it does update all linked data sources and graph templates......[/b]

Hi,

thanks for your help.

When I try to import the template I get an error message
Error: XML: Hash version does not exist.

What does it mean ?

snmpwalk is working for the switch. The Temp and FAN values are all correct.

I am using 0.86i - so that is the problem with the import.....have you saved the xml-file at .../resource/snmp_queries ?

All interfaces will be queried over the xml-file....so it seems that this file is missing

HI,

you mean the file brocade_interfaces.xml from the original source ?
It's there
sequoia:/usr/share/cacti/resource/snmp_queries # ll
total 24
-rw-r--r-- 1 root root 5472 Sep 5 09:20 brocade_interfaces.xml

So what I've done:
I've imported the templates and copied the file above into the resource/snmp_queries
folder. I have added a new device and I'm able to monitor fan and temperature.

The log file shows no error.

Can I call the xml file from the cli to get more informations what's going wrong ?

Bye, Peer

OK,

as expected: my fault. Somehow the data query was NOT set to snmp....
Don't know how this could happen. Now all 32 ports are found.
Waiting for the graphs ....

Thanks a lot !

Hi,

I'm now seeing all devices, but creating a graph is not working correctly:

RRDTool Command:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="Brocade 3- Traffic Port 1" \
--rigid \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="bits per second" \
--slope-mode \
DEF:a="/var/lib/cacti/brocade_3_traffic_in_230.rrd":traffic_in:AVERAGE \
DEF:b="/var/lib/cacti/brocade_3_traffic_in_230.rrd":traffic_out:AVERAGE \
CDEF:cdefa=a,8,* \
CDEF:cdeff=b,8,* \
AREA:cdefa#00CF00:"Inbound" \
GPRINT:cdefa:LAST:" Current\:%8.2lf %s" \
GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:cdefa:MAX:"Maximum\:%8.2lf %s" \
COMMENT:"Total In\: 0 bytes\n" \
LINE1:cdeff#002A97:"Outbound" \
GPRINT:cdeff:LAST:"Current\:%8.2lf %s" \
GPRINT:cdeff:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:cdeff:MAX:"Maximum\:%8.2lf %s" \
COMMENT:"Total Out\: 0 bytes"

RRDTool Says:

ERROR: opening '/var/lib/cacti/brocade_3_traffic_in_230.rrd': No such file or directory

In which step is "brocade_3_traffic_in_230.rrd" created (normaly) ?

Bye, Peer

Hi,

I would like to update my brocade template with the newer one so that I can see the throughput in bytes.

I put the new templates in the appropriate places (the one into the filesystem <cacti/ressources/ >), the host template I removed and imported the new one.

HowTo get the new template working (see additional the bytes transmitted) without destroying the old graphs?

Would it be possible to expand the template to see two results (Rx bytes and Tx bytes per port) seperately?

Thanks for help,

cheers, JUS

ame, can you please add to your post with the updated .xml for the 4100 and warn people that you have changed the default interfaces bits/s and the 95th percentile? I installed it and just spent 15mins getting all my graphs back to the standard formats we use.
