Hello Harshad,
First it is good to know which alert is specifically triggered, after that you can take actions that are related to you alert. Things to take into account beforehand are the following:
- did you release recently a new feature
- can you see in the metrics if this is a trend over a longer period or a spike
- did you upload a big amount of data recently
- did you migrate your mendix project to a higher version
For more information it is good to read the following:
alerts: https://docs.mendix.com/developerportal/operate/receive-alerts/
metrics: https://docs.mendix.com/developerportal/operate/metrics/
Good luck and if you have more question please provide some more details!
