+
My Database Instance is not performing as expected.
20
+
21
+
## Possible causes
22
+
23
+
- High data loads
24
+
- High incoming traffic from specific apps or websites
25
+
- Huge or sub-optimized SQL queries
26
+
27
+
## Solution
28
+
29
+
You can [Monitor usage metrics on Cockpit](/managed-databases-for-redis/how-to/monitor-databases-cockpit) to check if the usage is nominal.
30
+
31

The Database Instance can be impacted by high data loads or unexpected high traffic from an app or website, for example. You can [scale up your Instance](/managed-databases-for-redis/how-to/scale-up-a-database-for-redis) if necessary.

32
+
- Check if the usage is regular. Database Instance can be impacted by high data loads or unexpected high traffic from an app or website, for example

- Check the Database Instance logs for any unusual or suspicious activity
