    when have you added it? 1 hour back at least?
    if so then logs

    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

    Hi,

    data collection from your switches takes too long.
    Can you try the following steps? It should help.

    1. increase data collection timeout
    Just put line "export LAN_DATA_COLLECTION_TIMEOUT=900" to etc/.magic

    cd /home/stor2rrd/stor2rrd # or where is your STOR2RRD working dir
    echo "export LAN_DATA_COLLECTION_TIMEOUT=900" >>  etc/.magic

    2. re-schedule LAN agent in the crontab
    crontab -e

Change this line:
    # LAN
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/lpar2rrd/stor2rrd/load_lanperf.sh >/home/lpar2rrd/stor2rrd/logs/load_lanperf.out 2>&1lpar2rrd/stor2rrd/logs/load_sanperf.out 2>&1
    to:
    0,10,20,30,40,50 * * * * /home/lpar2rrd/stor2rrd/load_lanperf.sh >/home/lpar2rrd/stor2rrd/logs/load_lanperf.out 2>&1


    Let it work about 2-3 hours and let us know if that helped.

    tomlee, 
    your comments are not confusing, but I think you have a different problem. Have you tried configuring v2c snmp version?
  • Karel
    Karel
    Hi guys,

    it looks like these are 2 different issues.
    However the maximum timeout limit is 900 (15minutes) for variable LAN_DATA_COLLECTION_TIMEOUT. So do not use greater value then 900.

    1. Maks
    Connection test passes fine, but data collection from your switch takes longer then 15 minutes. This should not happen. Maybe there is an issue with firewall.

    @Pavel Can you pls follow it up? Thanks.

    2. tomlee
    We have found a bug when is snmpv3 used. We are working on a fix. We will let you know.

    Hi, 
    thanks.
    i can't use snmp2c because of security policy

    i suspect that my output is also huge nexus7000 with over dozen extenders

  • Pavel
    Pavel
    Mark,

    are you sure that you have properly allowed network connection to the switch?
    we have already seen that one snmp query goes through the firewals but when there is many of them they are blocked.

    can you install tcpdump and check what happens on the network, replace XX in below example by your one
    tcpdump -nl   -i enXX  'host IP_XXXX and udp port 161'  | tee x.log

    send x.log output after 10 minutes of running it

    Pavel,
    There are no firewalls in this network segment.
    In version v6. 00 this worked. I assume that the problem is not in the switches.

  • Pavel
    Pavel
    ok, we see a problem in the code, working on a fix right now, we will let you know soon.

    Hi
    I confirm - after install patch switches appeared in menu.

    PS: I have problem with LAN SWITCH  |  Nexus  |  corpo  |  FEX Port
    There are no picture / graph. Cursor is working all the time but if i click details i can see graph.
    I tested different web bowsers - the same.
    Should I create separate new discussion?
