809.0. "pa command" by JETSAM::WOODCOCK () Mon Mar 18 1991 12:58
Hi there,
Is this a user problem or an MCC problem? The command below is given to get
statistics for 15 minutes (right syntax?) in the past. Recording on the
entity counters follows.

1. This seems to be a user problem. The command syntax seems to
correct.
2. Historical Circuit Statistics requires the recording of
Circuit counters, Circuit Characteristics and Line
Characteristics. This is documented in the Pa Use Manual.
3. If you didn't record the Circuit or Line Characteristics,
you will get the exception "Requested data not
available for requested time".

| 809.2 | works ok now | JETSAM::WOODCOCK | | Mon Mar 18 1991 17:20 | 10 |
| Thanks, I had circuit counter and characteristics but not line characteristics.
All seems to be working now. I've doubled back thru the manual but still
can't find this info. I'm still using the doc set distributed from V1.1 EFT
training session. I guess it's time to get the latest and greatest. But I
am curious as to why characteristics need to be stored. Other than line
speed (which could be queried at the time of command) what is it that MCC
needs the characteristics for?

re .2

speed (which could be queried at the time of command) what is it that MCC
needs the characteristics for?
>>> Just for Line speed, as you correctly guess. Querying at runtime

>>> (Does the line speed change?).

| 809.4 | speeds do change | JETSAM::WOODCOCK | | Tue Mar 19 1991 10:52 | 21 |

Actually, yes it usually does over time (it always goes up!). Thinking
about it a bit more I tend to like how MCC has implemented this (although
it's more work to set up and requires additional disk space). Past tools
have the speed set statically with the computations being driven from the
single setting. When speed changes and the database was updated all
computations were based on the new value making the stats inacurate for
times before the change. MCC should deliver the proper numbers if the
user changes the speed and is careful enough to update and force a poll
on the characteristics at about the same time.
The circuit characteristics are probably used to check the data link
protocol to determine what the overhead is for that circuit and plug
it into calculations.

| 809.5 | I'll qar the documentation | TOOK::CALLANDER | | Wed Mar 20 1991 15:11 | 12 |
| Actually page 2-7 of the PA manual states (in the table) that:
"You must have recorded all attribute partitions for:"..."the circuit
and for the line the circuit is on."
In reality this needs to be corrected, for example you don't need to
record the reference attributes of the entity to be able to calculate
the statistics.
I will qar this; and yes this was the only place I found the info in
the manual.
