@tom Sorry... off to the coffee machine...

It seems the dashboard layout changed recently.

I am looking at "Main Dashboard" for a monitored database. I have the following panes:

• Latest Status (13 panels)
• a new unlabelled one that says "CPU: Unknown • Memory: Unknown • OS: Unknown"
• General info (3 panels)
• Database I/O (3 panels)
• Transactions & Locks (3 panels)
• Record activity (3 panels)
• Network metrics (3 panels)
• Async Writers Statistics (3 panels)

There used to be panes for BI and AI info. Have they been relocated? Will they be returning?

@tom said in SQL Servers are double-counted in 3.141x:

That's kind of dumb. Who the heck coded that?

case statements are hard.

dc/dashboard.p:

case  _Connect-type:
...
  when "sqsv"  then tt_Dashboard.con_sqlServ = tt_Dashboard.con_sqlServ + 1.
...
end.   //case
if _Connect-type begins "SQSV" then tt_Dashboard.con_SQLServ = tt_Dashboard.con_SQLServ + 1.

This may also be in previous versions; I haven't checked.

@tom said in Alert re lkHWM near lkTableSize:

Regarding the specific alert: there is a lkTblPct field which I use for a similar purpose. Rather than the HWM it reflects the locks in use at that moment. In some ways that is better -- the HWM sticks around until you restart and if something went bump in the night is going to keep alerting once you hit the threshold.

Good to know, thanks.

Maybe this belongs in "Roadmap" rather than "Using", but anyway...

Looking at alert.cfg:

#
# Metric Type Compare Target Sensitivity Notify Message              Action
# ====== ==== ======= ====== =========== ====== ==================== =======================
# LogRd   num       > 100000         3:5 Always "Hit Ratio &1 &2 &3" alert-message,alert-log
#
# Metric        The ui-det name of the field being monitored.
#
# Type          Data type -- char or num (string or numeric).
#
# Compare       Operator  -- >, <, =, <>, <=, >=
#
# Target        The threshold value of the metric to be tested.

Since it isn't stated explicitly, does "Target" have to be a constant? Could it be another metric of the same data type as "Metric"? Or an expression on constants or metrics (e.g. lkHWM * 0.8)?

Use case: let's say I want to configure an alert to fire when the lock HWM is getting close to -L, and have it work regardless of the value of -L, which could possibly vary over time or from one DB to another. Is that possible? Or do I just need to decide which number (say, 7000) I care about and configure it to alert when lkHWM > 7000?

Food for thought: the alerting mechanism would become more powerful if the target values could be dynamic in some way. Maybe passed to the back end via the API.

Cool, thanks.

Do you similarly flag tables where table reads are very high compared with the reads of their indexes? The calculations would be more involved but it might be useful.

For reference, the non-essential audit indexes (which are often purposely deactivated, except in audit archive DBs):

_aud-audit-data._AppContext-Id
_aud-audit-data._Connection-id
_aud-audit-data._Event-context
_aud-audit-data._Event-group
_aud-audit-data._EventId
_aud-audit-data._Userid
_aud-audit-data-value._Field-name

Possible bug: "%" must be invoked twice to have effect

I start pt3.141x against a DB, and Sample Type is "Rate/Interval" (as expected). When I hit "%" and select "Raw/Summary" and F1, the stats don't change. It says "RAW Summary" at top left but the stats are still interval rates. Hitting spacebar to refresh doesn't help. When I hit "%" and select "Raw/Summary" and F1 a second time, the raw stats appear as expected.

It appears this is the case for any changes in Sample Type. Changing back from "Raw/Summary" to "Rate/Interval" has the same issue, as does changing to "Cumulative/Summary".

Ok...

Do something different. (Please.)
