Description

Ive noticed in the metrics page that can be used with prometheus, HTTPS servers that dont have a valid signed (but still in date) certificate are displayed as expired despite having Ignore TLS/SSL error for HTTPS websites enabled in the advanced section of the monitor.

Additionally, ive noticed that monitors that use the push type display as down too (see attached screenshots for both)

Im not sure if this is intended behaviour or not, which is why im making this issue

Im using the latest nightly build with docker (1.13.1-nightly)

Monitor using push showing as up in the web UI:

Monitor showing as down in the /metrics page:

Monitor with a self signed/unknown CA certificate showing as not expired and displaying the expiry date in the web UI:

Monitor with a self signed/unknown CA certificate showing as expired but still displaying the expiry date on the stats page:

👟 Reproduction steps

Add a HTTPS monitor using a self signed certificate making sure that the Ignore TLS/SSL error for HTTPS websites is enabled and it should say as up and have the certificate expiry time. When looking at the /metrics page it will show as expired (0) but still have the expiry date

For the push monitor, add one and ensure that its being pushed to and showing up in the web UI but in /metrics it will show as down (0)

👀 Expected behavior

The certificate info will respect the Ignore TLS/SSL error for HTTPS websites option for the monitor in the /metrics page and display the same info as the web UI

The push monitor should follow the status in the web UI (up or down)

😓 Actual Behavior

For self signed/unknown CA certificates the monitor displays as expired in /metrics but valid in the web UI but still displays the expiry date

For push monitors, the monitor is displayed as down in /metrics and up on the web UI

I am having the same problem. Have you found a workaround? If not, I will try solving this one in the near future.

EDIT: actually, for me its a bit different. It shows when its down, but when its back up its gone from the metrics page.
