Cisco :: LMS 3.1 Inventory Collection And Polling Causing High Cpu
Jun 23, 2011
I have 3560-24PS-S (ios version 12.2(35)SE1) that have high CPU (almost 100%) use at every inventory collection (each sunday) or polling (each day 6 a.m) during 2 or 3 minutes.
I read on the forum, that this could be due to some mib object polling failure, and could, perhaps, be solved by upgrading the ios version or configuring view preventing the poll of the problematic object.
But what view to configure ?Is there well known MIB objects to filter ? Which ones ? I did not see any bug related to my IOS version and this behavior in the bug toolkit ... I join some sh commands (unfortunately done when no problem). I will try to obtain the output of the sh command when the pb occurs.

On our CiscoWorks 2000 installation, running on Solaris with LMS3.2 and RME4.3.1, we noticed a few weeks ago, that the job "Inventory Collection" needs more and more time to finish. At the moment the job execution time is as high as 8 hours, compared to 3 hours before. When we look at the network traffic during job execution, we see after the collection phase (~3h) several hours with no traffic together with a very high CPU load. I mean to remember that this job used to complete around 15 minutes after data collection phase. Restarting the application and rebooting the system didn't work.When we look in to the IC_Server.log, we find devices with a completion time of over 20'000 seconds. Increasing from day to day. [code]
Affected devices are Cisco Nexus 5548P. We tried to delete/add these devices. That works for a few days, then the runtime starts to increase again.
Are we hitting a bug? And is it possible, as a workaround, to exclude devices from only the Inventory Collection?

We have LMS4.0 monitoring 100+ devices. In that collection we have 2 4506e switches. The switches are identical,but one is inventoried successfully and the other always fails.Both have verified their credentials. The 4506e failing inventory is the only device not being inventoried.I looked at other post and increased snmp timeout with no effect.

I reinstalled CiscoWorks LMS (Windows 2008 R2) updated th LMS with all availible devicepackages and imported all devices with a xml bulk import of the former installation. Now I am frustrated.... because after the reinstallation LMS has problems collecting the inventory data.The inventory collection for one local device (Cisco WS-C3560-8PC-S) starts and nevers stops.... I have to stop the ICserver to stop the inventory collection.
I have only 4 of nearly 1800 devices where it was possible to collect the inventory information.All the rest is supposed to unreacheable...Reports> Inventory>Management Status>Unreachable Devices.But if I take one of the devices which is reported to be unreacheable and do a device diagnostic (Monitor> Troubleshooting Tools> Troubleshooting Workflows) says it is reacheable...
The inventory does not appear in the "Collector Status"?

When I do an Inventory Collection, the job doesn´t work with some devices and I have to restart the server. The job doesn´t fail but the log ICServer.log doesn´t got any information and it works for hours and hours and when it finally stops I can see that devices are not attempted.
I have done some succesfull Inventory Collections with Cisco 3750 switches and 805 routes. I have tried witch Cisco 2811 routers and 2950 and 2960 switches but it doesn´t work.
I have tried to update my LMS4.0.1 but it doesn´t find any actualization. However, in the Cisco download page there are some patches.

The following messages we get:
DCMA0055: URN_NOT_FOUND : urn "JRM" : Not found !!
DCMA0077: Could not create job. Check dcmaclient.log for more details.
Someone recommend to remove the following files ctmregistry and ctmregistry.backup.Will this fix the issue?

A customer reported that their router experienced spikes (high cpu utilization) every 4 hours and claims that it is caused by snmp polling of the Ciscoworks server.
The process SNMP engine is the process that causes these spikes .We think that the job responsible of this periodic high CPU utilization. It's called "Vrf Collector Job" and it's runnning every 4 hours.Below the result of show stack PID and show version

I'm attempting to create an erspan session between a Nexus 5000 and 6500 to get traffic from a FEX interface on the 5000 over to a sniffer off of the 6500. The Nexus and 6500 are directly connected with a 10G link, but I added a separate 1G link between the two for the erpsan traffic. I created a routed interface on the 6500, and and SVI on the Nexus. The Erspan session came up, and looked ok from both sides, but as soon as we got a burst of traffic this morning the CPU on the 6500 spiked to 99%. I used 'debug netdr capture rx' to determine the traffic was coming in from the erspan port and subsequently shut down the new interface on the 6500. why this caused a CPU spike? Here are the relevant configs from each device:
Nexus:
vrf context NetOps!
interface Vlan123
no shutdown

Recently me and my girlfriend have been having issues with in game latency, receiving pings close to jittering to well over 300 where they were formerly in the 30-40s to identical servers. We live with a Chinese housemate who is extremely conscious of her privacy/personal space, we noticed a dirge of active ports on the router (both TCP and UDP) which seemed to have no association with any major application and assumed it was the old P2P boogie-monster. She is the only one who uses Wifi, an upon briefly deactivating the Wifi, all ping issues were instantly resolved. The bizarre thing is we still have plently of up/download bandwidth, I mean we're not swimming in a fibre optic connection but still a relatively healthy 1MB dl/70KB/s ul, more than enough for gaming.Deciding we needed a better idea of what was going on in the network, we downloaded Wireshark. We discovered a couple of things that might mean something, they might mean nothing at all:Firstly there was a deluge of random ARP requests coming from the suspect IP, something along the lines of:"who has 192.168.0.(random number) Tell (suspect computer's IP)"repeated over and over in bursts. A little googling found us this: Has Your Network been Now given that she is Chinese and is probably exposed to a lot of Chinese websites, is there any chance that this could be the root cause - could it drown the network to the extent that it produces terrible pings?Secondly there have been an inordinate amount of name queries coming from her IP to 192.168.0.255 (broadcast channel), they generally take the form of:
NBNS92Name query NB WPAD<00>
or
NBNS92Name query NB ISATAP<00>
and occasionally, it will name query my network id, leading to: (her ip being 192.168.0.3)
2144211275.734470000192.168.0.3 192.168.0.255NBNS92Name query NB (my id)<20>
2144231275.739314000192.168.0.3 (my id)TCP6658451 > netbios-ssn [SYN] Seq=0 Win=8192 Len=0 MSS=1460 WS=4 SACK_PERM=1
2144251275.741325000192.168.0.3 (my id)NBSS126Session request, to (my network id)<20> from (her network id)<00>
2144271275.744124000192.168.0.3 (my id)SMB213Negotiate Protocol Request
[code]....
Now combine this with the sometimes 9-10 active ports our router assigns to her IP (which don't appear to relate to anything according to numerous port id sites), does this send out a red flag to any of you? I realize it would be so much easier if I could get access to her computer, but as I said, she is very private and timid and doesn't seem to like even having people in her room, let alone letting them use her computer.

I'm thinking of purchasing a Cisco Linksys EA6500. I need a router that can one monitor bandwidth used by device. Keep exceeding our ISP's network bandwidth allocation, need to identify the devices that are causing this high usage and be able to do so from the router. Does the EA6500's standard software support this, is their router software one can obtain for the unit that does this or is there another home router option that can perform this function?

We use LMS 3.2 with the latest patches. In IPM we have a couple of collectors (availabilty latency etc) and reports for our customers.
The polling interval for all collectors are working hour 7:30 - 18:00 Mo - Fr.
Unfortunately the polling detail is not included in the PDF report. Is there a way to include this information in the report.

Just purchased a Cisco SG200-26 (non-PoE version).
It works great, but since hooking it up to my network, my Synology NAS won't hibernate.
So I went and checked if the switch was polling, and indeed it is. Every 1-2 seconds, the activity LED on all connected ports, flashes simoultaneously.
When the LED on the switch flashes, the network LED on my NAS also flash. So I'm prone to think the switch is polling the entire network every couple seconds.
I've tried disabling Spanning Tree, and other other options that could relate to the issue, but without any luck.

I am having issues with monitoring our Cisco ASA5505 devices with "SolarWinds Orion NPM 10.2" through the use of SNMPv2. On some devices we see that SNMP polling stops and that the ASA's interfaces would show up as unknown - usually when the link to the device goes down/up or after a random ammount of time. At that point SNMP polling data is no longer updated and all we can rely on is ICMP for device status. I can resolve the issue by restarting the remote ASA OR restarting the SolarWinds server after which polling resumes. We are only seeing this behaviour with our remote ASA's.
Our setup is as follows:
Head End: Cisco ASA 5520 [ASA 8.3(2)]
Remote: Cisco ASA 5505 [ASA 8.3(2)]
I have found a SolarWinds article listed below that possibly identifies the issue that we are having but am not sure where to start.

Today I've received reports of slow internet access/activity and have noticed myself that it seems a bit slow today. On the dashboard of our asa 5510 the "outside interface" traffic usage is running constantly high. It's at the top of the graph. How can I tell what is causing the spike in utilization. It usually runs at about 1500-2000 Kbps, and now it's up over 10,000.

We installed a solution with 2 Cisco 2801, BGP multihomed failover.
1) The router which is currently getting all the traffic gets to 55% to 60% of CPU usage when handling 40 SIP/RTP streams . This equals 10Mbit up/10Mbit down and it showed around 5800 packets TX and around 5800 packets RX, with a majority of them CEF switched. As those figures are way less than the performance figures published by Cisco, we wonder if we made any mistake in setting up our router, or if we can do something to improve the router setup.
2) Does it have an impact on router performance if we increase/decrease RTP packet size, thus increasing or decreasing the pps relative to the consumed bandwidth?
3) If it is not possible to improve router configuration, we also wonder about possible replacement units for those routers. Would a 2901 do a good job? By how much would it rise the capacity? What other models would you recommend if we plan to rise the number of concurrent calls by a factor of 4 or even 8 times of what we have now (so up to 48000 pps and 80Mbit).
Here is what we tried:
- ip route-cache same-interface does not seem to improve anything
- ip flow ingress on or off makes no difference
- disabling the inbound ACL on fa0/0 seems to reduce load by 10%, although I don't understand why - a very high percentage is CPU interrupts, and ACLs are process switched, or not?
- we tried following the Cisco guide for high CPU due to high interrupts, with no success
Here are some usage statistics:
The graphs that we plot via SNMP show a propotional growth/increase of CPU and bandwidth (and thus pps) At the highest loads, we had a bit more than 55% CPU utilization with more than 50% interrupt CPU.
CPU utilization for five seconds: 36%/30%; one minute: 30%; five minutes: 30%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
127 13140 954 13773 2.00% 0.29% 0.07% 194 SSH Process
