"show ip sla history" empty. ASR1006

Hi all,

I want to do something with IP SLA and started by estabilishing a baseline.

I'm trying to check history on an ASR. I tested same config on a 3845 and was forgetting the "history filter all". After this I could see history table on 3845 but still history is empty on the ASR1006. The operation started because I can see information with "show ip sla statistics".

Anyone can help me to know if i missed something or maybe this is not supported in ASR1006?

Thank you

"show ip sla history" empty. ASR1006

I am not too familiar with the ASR but have you set up history collection within your SLA's?

history distributions-of-statistics-kept size

history enhanced [interval seconds] [buckets number-of-buckets]

history hours-of-statistics-kept hours

history statistics-distribution-interval milliseconds

History Statistics

IP SLAs maintains the following three types of history statistics:

  • Aggregated statistics--By default, IP SLAs maintains two hours of  aggregated statistics for each operation. Value from each operation  cycle is aggregated with the previously available data within a given  hour. The Enhanced History feature in IP SLAs allows for the aggregation  interval to be shorter than an hour.
  • Operation snapshot history--IP SLAs maintains a snapshot of data for  each operation instance that matches a configurable filter, such as all,  over threshold, or failures. The entire set of data is available and no  aggregation takes place.
  • Distribution statistics--IP SLAs maintains a frequency distribution over  configurable intervals. Each time IP SLAs starts an operation, a new  history bucket is created until the number of history buckets matches  the specified size or the lifetime of the operation expires. By default,  the history for an IP SLAs operation is not collected. If history is  collected, each bucket contains one or more history entries from the  operation. History buckets do not wrap.

Note

The IP SLAs UDP jitter operation does not support the IP SLAs History feature (statistics history

buckets) because of the large data volume involved with UDP jitter operations. This means that the

following commands are not supported for UDP jitter operations: history buckets-kept, history filter,

history lives-kept, samples-of-history-kept, and show ip sla history.

* The MIB used by IP SLAs (CISCO-RTTMON-MIB) limits the hours-of-statistics kept for the UDP

jitter operation to two hours. Configuring a larger value using the history hours-of-statisticshours

global configuration change will not increase the value beyond two hours. However, the Data

Collection MIB can be used to collect historical data for the operation.

Hope this is helpful to you.

Re: "show ip sla history" empty. ASR1006

Thanks ngoldwat,

I tryed the line you suggested and saw the text you provided before (please post original document link). I believe my intention is getting the operation snapshot history which is coming empty. however I do get something with "show ip sla enhanced-history collection-statistics" but still all values 0 (all error counters) and no ping values.

The configuration

ip sla 3

icmp-echo 8.8.8.8 source-ip 41.72.61.70

threshold 1000

timeout 1000

frequency 10

history distributions-of-statistics-kept 2

history enhanced interval 10 buckets 10

ip sla schedule 3 life 300 start-time now ageout 3600

Outputs:

Re: "show ip sla history" empty. ASR1006

Hey,

The full command is show ip sla history [operation-number] [tabular | full]

Here is a general link for IOS & NX-OS IP SLA along with one to History Statistics.

The Feature Navigator site is helpful as well.

If you still find yourself running into issues send the output of

-  sh mem

-  sh ip sla app

-  sh ip sla statistics aggregated

-  sh ip sla configuration

To debug:

-  debug ip sla error

-  debug ip sla trace

Re: "show ip sla history" empty. ASR1006

Hi ngoldwat,

The command without parameter is the same as tabular. But full I get output below:

re-ld-tcc-02_ASR1006#show ip sla history 3 full

Entry number: 3

History is not configured

But, I managed to find the problem. The configuration was missing "history lives-kept 1" which defaults to (zero)

re-ld-tcc-02_ASR1006(config-ip-sla-echo)#history ?

...

  lives-kept                        Maximum number of history lives to collect

...

re-ld-tcc-02_ASR1006(config-ip-sla-echo)#history lives-kept ?

  <0-2>  Life size value (default 0)

According to this:

...

lives: Number of lives maintained in the history table for the operation. If you specify 0 lives, history is not collected for the operation.

...

The default value of 0 lives means that history is not collected for the operation.

...

The command history filter all must also be configured (to get successes)

Thank you for your time ngoldwat and I hope this may be of help.

Regards

Mario
