The old alerts are text based, the new alerts should send html and graphs.

My issue turned out to be my spam filter interpreting the base64 encoded image as a uuencoded message, and then converting the uuencoded to ascii which resulted in all the + signs being replaced with + within the base64 encoded data.

Example

<img src="data:image/png;base64,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

HI,

I'm not getting any html or rrd graphs in the email alerts, is there a setting to enable this ?

Hi,

The image is included in the html you posted. It's an inline image, not all e-mail clients (notably Outlook) support this format.

All -

When I receive an alert based on an alerting check, I get a box at the bottom of the alert that looks like images are supposed to be included, but they aren’t able to resolve. Checking the email’s html, there isn’t a url included with the listed images. The html is attached. Any insight would be appreciated –

Thanks,

Matt
