- Log in to the Elasticsearch Add-On for Heroku console.
From the Elasticsearch Service panel, click the Quick link icon corresponding to the deployment that you want to manage.
On your deployment page, scroll down to Instances and check if the disk allocation for any of your Elasticsearch instances is over 90%.
- The available storage is insufficient for the amount of ingested data.
If your Elasticsearch cluster is unhealthy and reports a status of red, you can only delete unused data or reach out to email@example.com for help. If your Elasticsearch cluster reports a status of yellow or green, you might still take the following preventive steps.
Increase the disk size.
On your deployment page, scroll down to Instances and identify the node attribute of the instances that are running out of disk space.
Use the node types identified at step 1 to find out the corresponding data tier.
From your deployment menu, go to the Edit page and increase the Size per zone for the data tiers identified at step 2.
- Enable autoscaling to grow your cluster automatically when it runs out of space.
- Configure (ILM) policies to automatically delete unused data.
- Enable data tiers to move older data that you don’t query often to more cost-effective storage.
