Cisco Nexus 5548 Mib Download
Config: Type 'ifoctets' Table true Instance 'IF-MIB::ifName' Values 'IF-MIB::ifHCInOctets' 'IF-MIB::ifHCOutOctets' Address 'a.b.c.d' Version 2 Community ' Collect 'stdtraffic' Interval 60 Host 'localhost' Port '2003' Prefix 'collectd.' Postfix ' StoreRates true AlwaysAppendDS false EscapeCharacter ' For some other switches, for example older PowerConnect-switches everything works fine with configuration above, but not for PowerConnect 5548. The problem seems to be that while iterating over the values we encounter some oids in the Instance that does not have values.
A Management Information Base (MIB) is a collection of objects in a virtual database that allows Network Managers using Cisco IOS Software to manage devices such as routers and switches in a network. Network Management Software such as Cisco Works 2000 can be used to install MIBs.
For example: IF-MIB::ifName.3000 = STRING: tunnel1 while IF-MIB::ifHCInOctets.3000 = No Such Instance currently exists at this OID The debug output ends with: 2013-01-14 20:09:17 snmp plugin: csnmpcheckresleftsubtree: 2 of 3 variables have left their subtree 2013-01-14 20:09:17 snmp plugin: il-instance = `tunnel1'; 2013-01-14 20:09:17 snmp plugin: host = switch23; data = stdtraffic; Value 0 failed. It probably left its subtree. 2013-01-14 20:09:17 snmp plugin: host = switch23; data = stdtraffic; Value 1 failed. It probably left its subtree.
And nothing is written to graphite. I have played around some more and have seen what is probably the same problem with a Cisco 4500 as well. SNMP config is basically: Type 'ifoctets' Table true Instance 'IF-MIB::ifName' Values 'IF-MIB::ifHCInOctets' 'IF-MIB::ifHCOutOctets' Scale 8 Type 'ifpackets' Table true Instance 'IF-MIB::ifName' Values 'IF-MIB::ifInUcastPkts' 'IF-MIB::ifOutUcastPkts' Address 'a.b.c.d' Version 2 Community 'xxxxxxx' Collect 'stdtraffic' Interval 60 When debugging everything seems to be working until coming to the end. I have added a bunch of debugging code to try to figure out what's going on and I think what's happening is that instance suffix and the suffix used when getting the values are getting out of sync if an instance value exists while a value doesn't. This patch changes the snmp GETNEXT request behaviour implemented in snmp.c. The old implementation requested all OIDs using GETNEXT requests until all OIDs left their own subtree.
In cases were trees in a Data template are much longer than other trees the shorter subtrees were re-requested over and over again. The new implementation will only request OIDs that did not already leave their subtrees (see the oidtodolist implementation for details). This renders the function csnmpcheckresleftsubtree useless as the oidtodolist keeps track if all OIDs have finished. During tests against Cat6500 (CatOS/IOS) as well as Nexus5k (NX-OS) it looks as though GETNEXT requests (when requesting multiple OIDs like all 14 dot3Stats errors from Etherlike-MIB) can take about 5-10ms (CatOS 30ms) longer if they wrap to the next OID. This does not sound much but when collecting data for the Etherlike-MIB (that only has entries for physical interfaces) with a collectd 'Instance' variable in IF-MIB (that has entries for all physical as well as pseudo SVIs, VLANs. interfaces) this can make a notable difference (e.g.

For core routers that have all SVIs and VLANs but only some switches attached): IOS-Core-Router ifName 550 entries dot3StatsFCSErrors 70 entries - 480 entries. 10ms = 4.8s overhead CatOS-Access-Sw.
IfName 840 entries dot3StatsFCSErrors 490 entries - 350 entries. 30ms = 10.5s overhead After refactoring csnmpreadtable 'Instance' and 'Value' OIDs are now handled consistently (so no pointer-forward foo needed). It doesn't change any logic and data structures, though - so there should not be any impact to other functions.
The refactored code also fixes GitHub bugs and. This bug is due to reusing the status variable in following code section which might lead to errors if the subtrees are of different length: 1436 /. Calculate the current suffix. This is later used to check that the 1437.

There's little known feature, so called ZAP file ( ) - basically an inf file that can be specified in the group policy, same as MSI, and it will launch your executable with parameters. None of the 'answers' anywhere were working for me to get a standalone file to install chrome. In order to simply launch setup.exe by group policy, you don't even need this fake MSI. While this method does allow to deploy by group policy, it's missing practically all the advantages of Windows Installer (see ), and in many cases the administrator will have to repackage it into true MSI installation prior to deployment.
