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?
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
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.
* 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.
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.
