Hi All,
I use an snmp tool to monitor IP SLA results. This works fine, but in testing this setup i noticed
that the Monitors i setup created a new collection index after the previous has completed. This happens
after 720 operations.
See config below
rtr 10
type echo protocol ipIcmpEcho 1.1.1.1 source-ipaddr 2.2.2.2
frequency 5
rtr schedule 10 life forever start-time now
ROUTER#sh rtr collection-statistics
Entry number: 10
Start Time Index: 19:08:19.628 GMT Thu Mar 11 2010
Number of successful operations: 720
Number of operations over threshold: 0
Number of failed operations due to a Disconnect: 0
Number of failed operations due to a Timeout: 0
Number of failed operations due to a Busy: 0
Number of failed operations due to a No Connection: 0
Number of failed operations due to an Internal Error: 0
Number of failed operations due to a Sequence Error: 0
Number of failed operations due to a Verify Error: 0
RTT Values:
RTTAvg: 2 RTTMin: 1 RTTMax: 216
NumOfRTT: 720 RTTSum: 1800 RTTSum2: 144548
Start Time Index: 20:08:19.628 GMT Thu Mar 11 2010
Number of successful operations: 201
Number of operations over threshold: 0
Number of failed operations due to a Disconnect: 0
Number of failed operations due to a Timeout: 0
Number of failed operations due to a Busy: 0
Number of failed operations due to a No Connection: 0
Number of failed operations due to an Internal Error: 0
Number of failed operations due to a Sequence Error: 0
Number of failed operations due to a Verify Error: 0
RTT Values:
RTTAvg: 4 RTTMin: 1 RTTMax: 216
NumOfRTT: 201 RTTSum: 845 RTTSum2: 93617
Can anyone explain this to me? Is it important, and after each consecutive 720 operations is a new index created??
TIA
Stephen

Hello Stephen,
By default the 2 backets of 1 hour stats are maintained for an IP SLAs operation.
In your case 720 x 5sec (freq) = 3600 sec.
You could also check this via CLI using "show ip sla monitor configuration
It could be changed however, please check the following:
Configuring and Scheduling an ICMP Echo Operation with Optional Parameters on the Source Device

Hi Sergey
Thanks for replying. So it appears that there will always be two buckets, and when the second finishes a new one starts and the old deletes or purges. Thats perfect.
Thanks for your help
