Object count for GCS bucket subdirectory on monitoring dashboard

Question

I'm wondering whether I can create charts for 'Object count' of a sub directory within a GCS bucket. Ideally, I'd like to use the 'Group by' option. This doesn't seem to be possible. Is there an alternative way where I could create a chart for 'Object count' for a bucket sub directory?

Answer 1

The metric for the object count in Google Monitoring is defined as:

Total number of objects per bucket, grouped by storage class. [...]

So, if you want to create a metric that counts the number of objects in a sub-folder of a bucket you could:

List item

1. Create a Custom Metric
2. Create a script that list and count the objects
3. Write the data in the Custom Metric
4. Once you do it you can create a chart with the information.
