Got Unknown Object Identifier querying IP with public for sysName

lborek

Hi!

After upgrade to 2.5 config_check.sh returns problem with sysName MIB. Metrics are collected but verification fails. 

san_verify.pl:

Fri Feb 15 12:01:44 2019: Got Unknown Object Identifier querying 10.10.10.10:161 with public for sysName. No such file or directory/home/stor2rrd/stor2rrd/bin/SNMP_lib.pm:474 : No such file or directory

snmpwalk -v 2c -c public 10.10.10.10 1.3.6.1.2.1.1.5

Port          : 161 (default)

Timeout       : 5 seconds

  Check network connectivity and user access

Or sysName should be defined outside stor2rrd?

$ snmpwalk -v 2c -c public 10.10.10.10 sysName

sysName: Unknown Object Identifier (Sub-id not found: (top) -> sysName)

$ snmpwalk -v 2c -c public 10.10.10.10 1.3.6.1.2.1.1.5

iso.3.6.1.2.1.1.5.0 = STRING: "bl-blebleble"

Hi,

we probably found a small issue in san_verify.pl.
We'll send you a fix on Monday.

Karel

Hi Lukasz,

can you try this hotfix?

http://download.stor2rrd.com/patch/san_verify.pl.gz

Gunzip it and copy to /home/stor2rrd/stor2rrd/bin (755, stor2rrd owner)

-rwxr-xr-x 1 stor2rrd stor2rrd 4584 Feb 18 12:54 san_verify.pl

If your web browser gunzips it automatically then just rename it: mv san_verify.pl.gz san_verify.pl

Try again config_check.sh with this new file.
Let us know, thanks.

Hi, Just installed new san_verify.pl hotfix but issue is still alive. I have run config script test:

See config output:

=========================

=========================
  UDP connection to "192.168.1x.x" on port "161" is ok

san_verify.pl:

Thanks.

Works for me. @Ubuntu 16.4

stor2rrd@hostname:~/stor2rrd/bin$ ./config_check.sh 10.10.10.10

Hi,

@lborek, thanks for confirmation.

@igalvarez, can you try this snmpwalk command?

snmpwalk -v 1 -c public123 192.168.1x.x 1.3.6.1.2.1.1.5

igalvarez

Hi, find below output of snmpwalk

First, command failed:

[stor2rrd@lpar2rrd:/home/stor2rrd/stor2rrd/bin] snmpwalk -v 1 -c public123 192.168.126.5 1.3.6.1.2.1.1.5
ksh: snmpwalk:  not found.

But with full path it worked:

[stor2rrd@lpar2rrd:/home/stor2rrd/stor2rrd/bin] /opt/freeware/bin/snmpwalk  -v 1 -c public123 192.168.x.x 1.3.6.1.2.1.1.5
SNMPv2-MIB::sysName.0 = STRING: SW_BLADE_1

Karel

Hi @igalvarez,

what is your version of stor2rrd?
It looks like you have older version than 2.50.

/home/stor2rrd/stor2rrd/bin/SNMP_lib.pm:474 : No such file or directory

igalvarez

Hi,

I have upgraded to 2.50 last week. See below:

[stor2rrd@lpar2rrd:/home/stor2rrd/stor2rrd/etc] more stor2rrd.cfg
#
# STOR2RRD main configuration file
# STOR2RRD home : http://www.stor2rrd.com
version=2.50


# Update following parametrs
############################

# User for storage access
# Valid only for SVC/Storwize/FlashSystem, XIV, HUS, DS8000, 3PAR storages
# Rest of storages have users defined per storage in etc/storage-list.cfg
  STORAGE_USER=stor2rrd

# WWW directory where the tool places graphs, directory must exist before the first run, make sure
# that rights are correct
# Directory has to be configured in the WEB server
  WEBDIR=/home/stor2rrd/stor2rrd/www

igalvarez

Also, see upgrade log:

[stor2rrd@lpar2rrd:/home/stor2rrd/stor2rrd/logs] cat stor2rrd-install.log-21561826
Product upgrade under user : "stor2rrd"

Where is the product actually located [/home/stor2rrd/stor2rrd]: Backing up original version : 2.41 to /home/stor2rrd/stor2rrd/BACKUP-INSTALL/stor2rrd-2.41
Saving actual configuration
Copy new version to the target destination
Copy GUI files : /home/stor2rrd/stor2rrd/www
Configuring new stor2rrd.cfg
Setting file/dir permissions, it might take some time in huge environments
chmod -R o+r,o+x /home/stor2rrd/stor2rrd/data



Upgrade to version 2.50 is done

Wait about 15 - 20 minutes, to get fresh data from the storages

Then build a new GUI:

  cd /home/stor2rrd/stor2rrd
  ./load.sh | tee logs/load.out-initial

Wait for finishing of that, then refresh the GUI (Ctrl-F5)

Remember I'm running stor2rrd over AIX system.

Hi,

strange, in your output from config_check.sh is the same error as lborek had got with older version of san_verify.pl.

/home/stor2rrd/stor2rrd/bin/SNMP_lib.pm:474

Can you check the filesize?
This output pls:

ls -l /home/stor2rrd/stor2rrd/bin/san_verify.pl

igalvarez

[stor2rrd@lpar2rrd:/home/stor2rrd/stor2rrd/logs] ls -l /home/stor2rrd/stor2rrd/bin/san_verify.pl
-rwxr-xr-x    1 stor2rrd staff          4584 Feb 19 16:50 /home/stor2rrd/stor2rrd/bin/san_verify.pl

Karel

Hi,

only config_check.sh for this switch does not work? Do you see fresh data for this switch in the stor2rrd GUI?

igalvarez

Hi,

No, config_check to this switch give the same error of my first post.

No, there's no data in GUI after upgrade to 2.50

igalvarez

Can I roll-backstor2rrd to version 2.41?

Pavel

it will be different issue,

sends us logs before rolling back

Note a short problem description in the text field of the upload form.

cd /home/stor2rrd/stor2rrd # or where is your STOR2RRD working dir
tar cvhf logs.tar logs tmp/*txt
gzip -9 logs.tar

Send us logs.tar.gz via https://upload.stor2rrd.com
You might even attach screenshots when it helps in understanding of the issue.

igalvarez

Logs uplodaded.

Thx pavel!

Karel

Hi,

can you send us the output from this?

time /opt/freeware/bin/snmpwalk  -v 1 -c public123 192.168.x.x 1.3.6.1.2.1.1.5

It looks like there is some issue with timeout.
Snmpwalk command works, but snmp requests we use ends on timeout.
Timeout for each request is set to 5 seconds.

igalvarez

Hi,

can you try this new file as a fix?

http://download.stor2rrd.com/patch/SNMP_lib.pm.gz

Gunzip it and copy to /home/stor2rrd/stor2rrd/bin (755, stor2rrd owner)

-rwxr-xr-x 1 stor2rrd stor2rrd 19037 21. Feb 09.06 SNMP_lib.pm

If your web browser gunzips it automatically then just rename it: mv SNMP_lib.pm.gz SNMP_lib.pm

Send us output from config_check.sh, thanks.

igalvarez

Worked Perfectly.

As always, one of the best support ever.

Thanks

Karel

Hi,

thanks for confirmation.

NOTE: Issue was caused by using another community string than default "public".
This fix will be included in the upcoming version 2.51.

igalvarez

OK!... I'll open a new case for another issue we have with stor2rrd inn the other customer.Thanks much!
