I'm still having issues. Just downloaded v1.4 and uploaded to my centos 4 server...

Here is my snmp walk results:

Code: Select all

[root@wtw-man1 bin]# snmpwalk -v1 -c XxXxX 172.16.2.32 .1.3.6.1.3.1.2
[root@wtw-man1 bin]#
Here is the contents of the iostat.cache file:

Here is what happens what happens when i run the scripts from the machine locally:

Code: Select all

[root@q1-man1 ~]# /usr/local/bin/iostat.pl
[root@q1-man1 ~]# /usr/local/bin/iostat.pl .1.3.6.1.3.1.2
I'm stuck and not sure what to look at in the perl script. I have CentOS 4.6 and 4.7 and the results are the same. I have also tried 5.2 and 5.3 and the results generally are the same.

Hi
Working great, however all the graphs that contain read info are showing 0 reads.
Any updates on that ?
Thanks

Thanks so much for all of this, it works out very well as long as you have a small amount of disks.

I've hacked it up to support vxstat for grabbing stats from VxVM volumes and disks.

It's pretty crude, but it works for me on Sol9. Feel free to include it in the official version if you want. I only included 2 types of graphs, IO requests and times. There is 1 more type of graph you could easily make if you wanted to, as the parsing and data query is already setup to pull blocks transferred.


Otherwise YMMV.

Quick lil update,

I have hacked togeather the cronjob to handle a system with EMC multipath devices.

This will only work if you have labeled your disks per emc standard

/dev/emcpower**

set a cron to run the sh file.

Same here - CentOS 5.3 and no results with any of those OIDs.
Tried on RHEL5.3 and also no results.

If you do not get any output in Cacti (and it works when using snmpwalk on the command line), you could try increasing the SNMP timeout in Cacti. That worked for me.

All who have problems with Centos - check the logs selinux!
I used audit2allow and created policy file:

Code: Select all

module snmpdpassiostat 1.0;

require {
        type snmpd_t;
        type tmp_t;
        class file { read ioctl getattr };
}

#============= snmpd_t ==============
allow snmpd_t tmp_t:file { read ioctl getattr };
And now everything works !

I'm on CentOS 5.4 and I also have trouble getting this to work. SELinux is disabled so that's not the problem.
I can do the following:

Code: Select all

[root@server /]# /usr/local/bin/iostat.pl -g .1.3.6.1.3.1.2.3
.1.3.6.1.3.1.2.3
string
sdb
[root@server /]#
so the data is getting read and parsed all right. however the following doesn't work:

Code: Select all

[root@server /]# snmpwalk -v1 -c public localhost .1.3.6.1.3.1
End of MIB
In Cacti, I also see "no SNMP data returned" errors (obviously...)

I don't speak perl well enough to fix or even debug the script (except for placing some dummy print statements) and I do know almost nothing about the linux snmpd (I just did "yum install snmpd" and "service snmpd start" after I added the "pass..." line to the snmpd.conf)

Any help would be greatly appreciated
-Michael

*Edit: CentOS 5.4 x64 fully patched, snmpd 5.3.2.2, cacti 0.8.7e*
*Edit2: I modified the SNMP config to allow access from everywhere, now I can browse a whole lot of snmp subtrees ("snmpwalk -v1 -c public localhost .1 | wc -l" says 8523 lines) but the .1.3.6.1.3.1 subtree is not among them*

I'm trying to run this against Solaris 10 Sparc, and it's running from a ubu server 9

Below is the output of a verbose query

when i attempt to create the iostat graphs in cacti I get this:

+ Running data query [11].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/cacti/resource/snmp_queries/iostat.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.3.1'
+ No SNMP data returned

snmpwalk returns:

Timeout: No Response from <host>


iostat.pl seems to run and I have output in /tmp/iostat.cache

any ideas how to get this to work?

iostat query does not delivers results

Post by starfish »

Hi,

thanks for your nice work! I have installed the files and templates according to your readme file, but now I experience the same problem like some other people: after adding the new data queries to my device, the queries show 0 items and rows. I have spent some time on debugging and searching for advice, but so far without success.

On the Cacti web gui, verbose query (e.g. for "iostat - kBytes/sec") says:

+ Running data query [13].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/srv/www/htdocs/cacti/resource/snmp_queries/iostat.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.3.1'
+ No SNMP data returned
+ Found data query XML file at '/srv/www/htdocs/cacti/resource/snmp_queries/iostat.xml'
+ Found data query XML file at '/srv/www/htdocs/cacti/resource/snmp_queries/iostat.xml'
+ Found data query XML file at '/srv/www/htdocs/cacti/resource/snmp_queries/iostat.xml'

My iostat.cache looks like:

If I hit the green circle next to the data query or click the link to run the verbose query, I can see on the target server that a lot of snmp requests are received and answered (tcpdump output). I can see the corresponding traffic on the Cacti server, therefor my *guess* is, that data is received but not interpreted.

So what can be the reason for cacti telling me that no data is available? How can I find out what's wrong?

Thanks!

Re: Linux extended iostat template and scripts

It's possible to use this template to monitor nfs mount points? When we execute iostat, it only give me the local devices. Btw, I also tried to execute with -n option, but iostat command doesn't support -n option on my os. Thanks inadvance for your suggestions/comments.
