First, check your status page at https://www.algolia.com/status to see if a cluster that you're on is affected by an outage.
If there is no outage, check whether you see indexing operations coming through on the logs https://dashboard.algolia.com/monitoring/logs section of your application. Note that the individual logs are clickable, click a "batch" line, for example, to see detailed information regarding the payload and response.
Note these are truncated.
If you see indexing operations coming through this means that indexing is happening.
If you see an error, the error message should provide more information regarding the reason for the issue.
If you do not see any operations coming through at all, you should check your local logs or local error messages for issues.
If you're seeing that your updates are not immediately being reflected in your index, note that updates are asynchronous. If you've sent a large number of updates, or if you're on a shared cluster that is experiencing more indexing than usual, your updates may take longer to apply.
