Chart Y Limits — Email Notifications

Saved Charts can optionally be set up with minimum and/or maximum value limits, and send automatic email notifications.

This example chart will notify if regression coverage is below 95%.

Y Limits

Chart Y Limits can be set as:

Minimum value
Maximum value
Bounded (between minimum and maximum)
Wildcard (*) — asterisk

If the chart data is detected outside the limits, the creator of the chart will automatically get a notification email.

Users can set up threshold limits on charts, if they want to be notified with an email if a chart goes outside of the bounds.

Note: chart limits are currently only checked once a day, usually in the morning (ie 7am).

Chart Limit Scenarios

Charts can either:

Not check limits (default — no emails)
Send on fail
Send on pass/fail
Wildcard, send always (always pass)

Wildcard Limit — `*`

If either min or max limit are set to * (asterisk), this will change chart limit behavior to send daily emails on both pass and fail events.

If left as blank value, Simscope keeps the prior behavior, where emails are only sent if a limit fails.

Limit Values

The min and max limits can be blank, set to a number, or set to wildcard.

Limit Value	Example	Meaning
Blank		Blank (empty) string value. No limit (and no notification).
Number	`95.1`	Numeric limit value. Send fail email if chart value is outside this value.
Wildcard	`*`	Send pass email if value is within limit.

Limit Notification Behavior

Here is a table of limit configurations and whether they send emails.

Limit Min	Limit Max	Pass Email	Fail Email	Comment
.	.	.	.	Default — no limits
.	*	✅	.	Wildcard: notify always (note the chart always passes)
.	Number	.	✅	Maximum value chart — notify if above maximum
Number	.	.	✅	Minimum value chart — notify if below minimum
*	Number	✅	✅	Maximum value — notify on both pass/fail
Number	*	✅	✅	Minimum value — notify on both pass/fail

Pass Rate Example

For example, you can create a Pass Rate chart on a series of daily regressions, and set a minimum limit value of 0.95 (ie 95%).

If the regressions hit 93%, you would get an email.
If 95% or higher, no email is sent.

Example Chart with Limits

This example has set a Pass Rate minimum of 95% with pass notifications enabled.

If below 95%, the user will get a Fail email.
If 95% or higher, the user will get a Pass email.

→ With this example chart data, the user will get a Pass email, due to the pass rates being above the 95% limit.

Email Notification Example

This is an example limit failure email notification:

Email CC

By default, chart notifications are emailed only to the user who created the chart.

To optionally add additional email CC (carbon copy) to notify others of chart limit failures:

Click the blue mail envelopen icon next to Y Limits.
Type in one or more email addresses, separated by commas.

Note: you must Save the chart after adding the CC.

Notification Check Time

Charts are checked for limit values once per day.

See simscope.config

[chart]
# Enable daily checks (occur once per day).
# NOTE: this time is used for Regression Watch, Signature Watch, and Daily Charts.
autocheckschedule = "07:00 CST"

Note: since charts are only checked once per day, so if a chart goes outside of the bounds and is back within bounds when the check occurs, you will not get a notification.
