Hi Aigars,

its the same device its Dell EMC Isilon, but its build from 3 separate devices (all are the same).
BUt still understand why, when I had installed Zabbix 3.4.5 and used preinstaled template it was showing me only the corect amount of items, this one find so lot of it.

And the discovery doesnt work. Nothings was found.

OK understand so, I will add there only the needed.

Thanks.

The template just works fine. Just loaded this small device with your dump provided and values appear as expected I guess.

If this template is not working on your 192.168.54.241 then there is something wrong with 'net-snmp' package or its dependencies.

Hi Aigars,

I have added the template and let run the discovery for some hours but nothing.
I dont understand it. When I use the templates preinstaled in Zabbix, the discovery works perfekt, but your templates will not work.

And sorry I have make an mistake. I have sent you data from a wrong device. The sent data was a normal Win 7 Pro PC.
Now I have attached the data fron the NAS Storage: vnas2.zip
I start your template on the PC from which I have sent you the data. Will see if it will work there.

Thanks.

Just a little side topic in your apache2/error.log. Can you explain line:

Code:

 MIB search path: /var/www/html/zabbix/snmp_builder/mibs:/usr/share/snmp/mibs

Are you using this 'snmp_builder'? Is it working well?

How much MIB files you have inside '/usr/share/snmp/mibs'.
Plese show the configuration inside '/etc/snmp/snmp.conf'

A little bit it is working:
Custom-Storage-Discovery-2.xml

2000 items discovered.

Hi Aigars,

yes I use SNMP Builder.
After some changings it is working but it has some bugs or things which are needed to improve.
I have there all downloaded mibs with mib downloader and also I have there add about 20 my MIBs.

Code:

# As the snmp packages come without MIB files due to license reasons, loading
# of MIBs is disabled by default. If you added the MIBs you can reenable
# loading them by commenting out the following line.
mibs :
mibs +ISILON-MIB
mibs +ISILON-TRAP-MIB
mibs +LSI-MegaRAID-SAS-MIB
mibs +NET-SNMP-EXTEND-MIB
mibs +SUPERMICRO-HEALTH-MIB
mibs +SUPERMICRO-SMI
mibs +SYNOLOGY-DISK-MIB
mibs +SYNOLOGY-ISCSILUN-MIB
mibs +SYNOLOGY-RAID-MIB
mibs +SYNOLOGY-SERVICES-MIB
mibs +SYNOLOGY-SMART-MIB
mibs +SYNOLOGY-SPACEIO-MIB
mibs +SYNOLOGY-STORAGEIO-MIB
mibs +SYNOLOGY-SYSTEM-MIB
mibs +SYNOLOGY-UPS-MIB

I have downloaded the new template and set it. Will look what the discovery will find.

Hi,

Mainly the {#STORAGE_TYPE} filter has been removed.
I guess all calculated items should be supported by now.

Regards,

**Alfista** · 18-06-2018, 08:14

Hi Aigars,

OK and this has made so many problems??
Still are there the calculated items with Error - divide by zero (Mostly are it the MALLOC:xxx storages - Total space is 0). But this isn't a so big problem. The main problem is that it makes so many items ... And the filter for items with 0 size doesn't work.

Thnaks.

**aigars.kadikis** · 27-06-2018, 09:17

The RegEx works just fine which will take everything that is bigger than 0:

Code:

snmpwalk -v2c -cdevice1 127.0.0.1:1024 1.3.6.1.2.1.25.2.3.1.6 | grep -v "INTEGER: 0" | wc -l

snmpwalk reports 366*6=2196 + 5 general items = pretty much the same situation than Zabbixbix.

to choose something bigger than 0 I tested with:

Code:

[1-9]([1-9]+){6,99}

which will scope only SpaceUsed:

Code:

9*6 + 5 = 59 items

You can increase the item count by moving backwards:

Code:

[1-9]([1-9]+){5,99}
[1-9]([1-9]+){4,99}
..

Kind Regards,
Aigars

**Alfista** · 27-06-2018, 13:31

Hi Aigars,

If understand corectly I only need to play with the filter parameters:

Code:

[1-9]([1-9]+){6,99}

and specialy withe first number in {}?

What is the parameter wc -1 in the snmpwalk command?

By the way the snmpwalk on localhost (127.0.0.1) doesnt work by me. I cant find why, I have only time out.

Thanks.

**aigars.kadikis** · 27-06-2018, 13:43

That is right. You need to play with the Filter parameters in the discovery rule.

'wc -l' just counts the lines. Symbol after the dash is lowercase L, not number 1. The command just counts the lines.
IP address and community name (-c device1) needs to be replaced in your scenario. Yeah, you need to replace 127.0.0.1:1024 with your 192.168.51.241. Port is not needed.

about what results will be retrieved you can easily test in https://regex101.com/. just paste on the top this '[1-9]([1-9]+){6,99}' and in the second filed write a bunch of numbers each one in a separate line like:

Code:

Everything that is coloured will be passed forward (to create item in Zabbix).

Hi Aigars,

thanks for help. It reduced a lot of items. Now I have aroud 200.

I have tested it, but still have there items which has 0 and they aren't calculated items. It is by Total Space.
I have this filter applied to the memory discovery rule (added to the origal two filters with or/and) in original template and find that it doesnt shows the main memory.
Please can you help me what I have make wrong?
And how is possible to set that the discovery rule set correct name for memory and not #xxx where xxx is number?

Thanks.

**Alfista** · 16-10-2018, 09:56

Hi,

I have moved to the latest Yabbix 4.0 and this filter parameter {#STORAGE_USED} = [1-9]([1-9]+){4,99} will not work corectly, even set same as in release 3.4.
After I give this parameters to the discovery filter, then I dont receive any items.

Please cany you help me what I do wrong, or what is needed to repair that it work Zabbix 4.

Thanks.
