ucd/net snmp Device (Disk) I/O templates - Updated - v3.1

[paulbeard206]

It would be easier to work with just one archive, I think. If you were to upload a new one (not overwriting the old ones) with known good files, that might help.

One install is from source (FreeBSD ports) and one from rpm. Though this is a php-based app, no compilation or linking that I am aware of.

One other thing: I don't get those values (the reads/writes) exposed in my net-snmp-based installs. Am I wasting my time?

[Rodre]

What happens if you run:

Code: Select all

snmpwalk -v 2c host-ip -c community-name.1.3.6.1.4.1.2021.13.15

Replace host-ip with the ip address of the target host or localhost if you are running the command on the target host and replace community-name with the read community of the target host i.e:public

do you see UCD-DISKIO-MIB::diskIO related stuff?

[paulbeard206]

It looks like the ucd/diskio stuff has to be specified at build time. Once I get that done, I'll take another whack at this.

[jennifer]

rodre,
if I go console->data queries, There is no "ucd/net - Get Device I/O".
if I go console ->data templates->ucd/net - Device I/O (No Get) it says get SNMP data indexed.

Could this be the issue?

[paulbeard206]

See if this returns anything before you start. Now mine does.

Code: Select all

snmptable -v 2c -c community host diskIOTable            
SNMP table: UCD-DISKIO-MIB::diskIOTable

When I do the snmpwalk I do get similer output to Pauls. I can post if needed.

So I have some systems exposing the DISKIO values and it all looks good.

But I still can't get anywhere. I import the templates, add the query to the repository, generate a new graph, and get stuck on a screen that wants me

Create Graph from 'ucd/net - Device I/O'

with three blanks: Index Type, Index Value, Output Type ID.

Another question: would these counters need to limited to 32 bit (4294967296)? Right now, the template, after import, doesn't seem to include that.

I'm still hopeful I can use these templates rather than build this out from scratch. What information from me would help?

[Rodre]

Try this out:

1. Delete the graph template(s) from: Console -> Graph Templates

2. Delete the Data Template from: Console -> Data Templates

3. Delete the Data Query from: Console -> Data Queries

4. Delete the <path_cacti>/resource/snmp_queries/net-snmp_devio.xml file from the file system of the Cacti host.

5. Download the files below (updated to same file as the one in the original post)

6. Copy the net-snmp_devio.xml to your <path_cacti>/resource/snmp_queries/ directory of the Cacti host.

7. Import all the *_graphTEMPL.xml files using: Console -> Import Templates

Does that order work?

--Download removed - please download from initial post for version control-- Above instructions have been updated to reflect version 2

[paulbeard206]

I have never seen the data query associated with this set of templates: still no sign of it today. It wasn't there to be deleted and it didn't show up installing these new files.

[Rodre]

Is there an error when you import the Data-Query_Templ.xml file?

Prior to importing the above file do you have the net-snmp_devio.xml file in the <path_cacti>/resource/snmp_queries/net-snmp_devio.xml directory? For example it is in my /var/www/html/cacti/resource/snmp_queries/ directory. Are the access permissions for the file the same as the other "stock" files in that directory?

~Rodre

[paulbeard206]

I replaced the net-snmp xml file with the latest one, and then reimported the templates. All generated errors.

I also see errors importing

[success] ucd/net - Device I/O [update]
+ Unmet Dependency: (Data Input Method) Get SNMP Data (Indexed)
+ Unmet Dependency: (Data Input Field) Output Type ID
+ Unmet Dependency: (Data Input Field) Index Value
+ Unmet Dependency: (Data Input Field) Index Type
+ Unmet Dependency: (Data Input Field) SNMP Version (1, 2, or 3)
+ Unmet Dependency: (Data Input Field) SNMP Password (v3)
+ Unmet Dependency: (Data Input Field) SNMP Username (v3)
+ Unmet Dependency: (Data Input Field) SNMP Community
+ Unmet Dependency: (Data Input Field) SNMP IP Address

the xml file is in the correct place and the permisions are right. I added the Data Query, and it is able to parse it properly.

Has anyone had luck with this?[/code]

[Rodre]

I am beginning to wonder that myself, as I want to get this graphs Export -> Import functionality working before I export and share a bunch of other graphs that I have created that may be usefull to others.

Can someone from the Cacti team elaborate on the correct method/order to export templates and the correct/order to import them? Thanks.

~Rodre

[ajeskey]

Every time I have exported to post to the forums, I just

Console -> Export Templates

- Chose Graph Template
- Chose Graph Template to Export
- Check off Include dependencies
- Chose Save File Localy
- Click Create

What version of cacti are you using?

[Rodre]

I am using version 0.8.6f with all the recent patches (as of yesterday) and RRDTool v1.0.49 (Fedora 4 RPM).

Every time I choose the "Save File Locally" radio button and click on the "create" button, Internet Explorer gives me a wack of errors, so I usually just choose the "Output to the Browser (within Cacti)" radio button and then cut and paste the output to notepad. Maybe this is the error in my ways?

I need to try to export using another browser, what are you guys using as a browser?
