Hi - Brand new to Signoz. Just got it setup on a server but now have some questions. 1. We don't use Slack in our org. We use [Mattermost](https://mattermost.com/) -- Is there a way to have alerts go to systems other than Slack? 2. We have complex customer website visit, order count data stored in a table, segmented by a customer ID. Is there a way for us to monitor order counts by day, and send an alert if counts are outside a threshold? Seems like this is the perfect use case for Signoz, but not sure if it's possible with this kind of data. The data is stored in AWS S3.

1. We provide webhook APIs, should be able to configure alerts to mattermost through webhooks

OK, great

2. You should be able to do by sending custom metrics using opetelemetry APIs and then setting alerts on SigNoz Check docs on how to send custome metrics here • https://signoz.io/blog/introduction-to-opentelemetry-metrics/#the-opentelemetry-signals---logs-metrics-and-traces • https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/api.md

OK, great. Thanks @Pranay
