parameter not represent a number

[magikk]

Hello,

i don't succeed to view my CPU usage graph.The error is here:

Code: Select all

RRDTool Command:

I think you have already answered here:
http://forums.cacti.net/viewtopic.php? ... A#p231952
I don't think to understand well ...

Edit the graph template and select the last graph item. Select the correct data source item and save
R.

In graph templates,at the top i have "Cisco CPU Usage" , i click on it.
Then in "Graph Template Items [edit: Cisco - CPU Usage]" i have 4 items.And....?

Graph Item Data Source Graph Item Type CF Type Item Color
Item # 1 (5min_cpu): CPU Usage AREA AVERAGE FF0000
Item # 2 (5min_cpu): Current: GPRINT LAST
Item # 3 (5min_cpu): Average: GPRINT AVERAGE
Item # 4 (5min_cpu): Maximum:<HR> GPRINT MAX



Graph Item Inputs Add

CPU Usage Data Source

Thank you

For the last screenshot, we need the upper part. I need to see the reference to a valid data source
R.

[magikk]

Sorry, i don't think to understand exactly what you want,but the bottom screen is the exact continuation of the top one.
(If i click on the DataSource link , i have nothing concerning CPU..)




PS:
Just for information, i have deleted a few .rrd files (with cpu in their name) ,because i thought they were in double.I hope i have done nothing wrong..
Here is the content of my /var/www/html/cacti/rra directory.

I just added a 1erEquipement-5min-cpu in my dataSources , and added it to my graph Tree (and deleted the last one), and now i have again a CPU usage graph that is void.
So i need to follow the debugging procedure i guess.
That's why i check my cacti log file.
I find a :

Code: Select all

01/10/2013 12:55:02 PM - CMDPHP: Poller[0] Host[2] DS[35] WARNING: Result from SNMP not valid. Partial Result: U
01/10/2013 12:55:02 PM - CMDPHP: Poller[0] WARNING: SNMP Get Timeout for Host:'192.168.0.253', and OID:'.1.3.6.1.4.1.9.2.1.58.0' 

....but i don't know what to do with that OID.How can i know to what device he belongs to?
I tried to use the snmpget or snmpwalk command but usually that answered me that localhost was unreacheable...
If i try:

Code: Select all

snmpget -c cacti -v 2c 192.168.0.253 .1.3.6.1.4.1.9.2.1.58.0

I have: (192.168.0.253 is not the localhost).

Code: Select all

SNMPv2-SMI::enterprises.9.2.1.58.0 = No Such Object available on this agent at this OID

**************
What i don't understand also is if i have to run this command or not (from the debugging tutorial).All that i can say is that i am using root privileges for the shell and admin user for Cacti ...

Run the following command to cure this problem

chown cactiuser:cactiuser *.rrd

*************

Now my 5-min-cpu in debug mode is:

Code: Select all

Data Source Debug

/bin/rrdtool create \
/usr/share/cacti/rra/1er_equipement_5min_cpu_35.rrd \

RRA:MAX:0.5:6:700 \

And i have now (for 5 min cpu) in /var/www/html/cacti/rra directory:

Code: Select all

1er_equipement_5min_cpu_35.rrd 

(I have deleted : 1er_equipement_5min_cpu_29.rrd)

Maybe this could help ......

Sorry, i don't think to understand exactly what you want,but the bottom screen is the exact continuation of the top one.
(If i click on the DataSource link , i have nothing concerning CPU..)

I'm sorry, my request was not exact. I need a screenshot of the AREA graph item (the first one). I expect NOT to find a related data source - this is the root cause, then.

Here it is..

The output of

and

Posted: 2013 Jan Thu 10, 12:06 pm

does not match. The last one at least matches the screenshot you've send last.
The first output usually refers to an issue that I had in mind when asking for the data source.
The last output is syntactically ok (no error message), but data is missing.
These are different issues, so please tell us which one to look at
R.

My goal is to view hardware informations in a tree (cpu or ram ....) with snmp or netflow or whatever...I succeed it with localhost but not with the 192.168.0.253 device.
Now i have deleted The "CPU usage" graph from my "graph tree" and from my "graph management" because it wasn't working.
Then if i try again to add "Cisco CPU Usage" to my "Graph Management" with Host=1er_equipement(192.168.0.253) , i click on create , and because i am in debugging mode i have the screen that you see under this text.

Then i go to "Graph Tree" , i add (Graph>tree item value) : "1er_equipement-CPU Usage" (create).And the result is that in my graphs i don't have any "1er_equipement-CPU-Usage" graph.(This graph is just a link with nothing inside).

[magikk]

Then i try with "Netware CPU Utilisation", i add it to the "Graph Management".This time for "CPU Utilisation data source" i try "1er_equipement-Memory-Free(mem_buffers)
(because if i leave at none i have the message :ERROR: parameter '#FF0000FF' does not represent a number in line AREA:#FF0000FF:CPU Utilization)
I click on "Save".
I add "Netware CPU Utilisation" to "tree item", (create).And .....
I visualize the graph : "CPU Utilisation for 1er equipement", but do i have succeed because if i select for instance "ping host" in "CPU usage data source", i have the same graph that my ping graph?

Depending on the hardware you're polling at least one of those templates or both won't work.
They are able to monitor specific, device dependent OIDs that represent CPU usage for those types of devices only!

Some Cisco devices (there are so many of them) respond to the OID built into the Cisco CPU Usage template. But virtaully every other device in the world won't respond to this type of template.

As given by 2nd link of my sig, you are able to verify whether your target device responds to a given OID by issuing a specifc command from command line ... it's all explained at that link. Only when the target device is queried for the correct OID, it will respond with valid data.

So we have to check that first.

(and still: any graph debug that does not show at least one DEF statement won't work - it is broken)
