Overview of Healthwatch

Healthwatch allows you to monitor metrics related to the functionality of your Ops Manager platform.

For more information about each of these tiles, see the following sections below:

Overview of the Healthwatch Tile

Healthwatch then exports the collected metrics to dashboards in the Grafana UI, allowing you to visualize the data with charts and graphs and create customized dashboards for long-term monitoring and troubleshooting.

Healthwatch includes the following features:

Grafana: Allows you to visualize the collected metrics data in charts and graphs, as well as create customized dashboards for easier monitoring and troubleshooting

Alertmanager: Manages and sends alerts according to the alerting rules you configure

Canary URL tests for TAS for VMs apps

Counter, gauge, and container metrics for TAS for VMs from the Loggregator Firehose SVMs

The Prometheus instance that exists within your metrics monitoring system then scrapes the Prometheus exposition endpoints on the metric exporter VMs and imports those metrics into your monitoring system.

Healthwatch Exporter for TKGI exposes the following metrics related to the functionality of TKGI components and the Healthwatch Exporter for TKGI tile:

The following table provides version and version support information about Healthwatch:

Healthwatch v2.2 does not provide an SMTP server. You must use an external SMTP server when you configure alerts from Alertmanager or the Grafana UI.

Healthwatch v2.2 does not expose the UI for the open-source components Alertmanager and Prometheus because the UIs are not secure. However, you can access the UIs of the Prometheus and Alertmanager VMs for troubleshooting. For more information, see Accessing VM UIs for Troubleshooting in Troubleshooting Healthwatch.

Healthwatch v2.2 is not meant to be a long-term data store. It only stores data for six weeks.

Healthwatch v2.2 is not designed to capture all metrics from multiple Ops Manager foundations. For more information about the metrics that Healthwatch v2.2 stores, see Healthwatch Metrics.

The following list describes the problems that could arise when using Healthwatch v2.2:

Healthwatch v2.2 uses open-source components, including Grafana, Prometheus, and Alertmanager. VMware does not have direct control over how quickly feature changes and bug fixes appear in these components.

Healthwatch v2.2.5 uses the following open-source component versions:

v2.2.4

Release Date: September 21, 2022

[Feature Improvement] The MySQL Overview dashboard in the Grafana UI includes the MySQL Jumpbox VM persistent disk usage chart.

[Feature Improvement] When you re-deploy a highly-available (HA) Healthwatch installation with multiple Grafana instances, the second Grafana instance does not start updating until after the first Grafana instance has updated and re-starts.

Release Date: August 18, 2022

[Feature Improvement] When you configure an alert receiver for Slack, you are not required to configure the Alert receiver configuration parameters field. The only fields you must configure are Alert receiver name and Slack API URL. For more information, see Configure a Slack Alert Receiver in Configuring Alerting.

[Known Issue Fix] After you re-deploy an HA Healthwatch installation, the Grafana instance can load metrics data in the Grafana UI while multiple Prometheus instances update. This known issue fix improves upon the known issue fix in Healthwatch v2.2.2. For more information about this known issue, see No Data While Re-Deploying Highly-Available Healthwatch Installations below.

[Bug Fix] In the BOSH Director Health dashboard in the Grafana UI, the BOSH Director Status and BOSH Director Status History panels include the system_healthy metric.

[Feature Improvement] The default alert templates are updated to better display grouped alerts.

[Feature Improvement] The Logging and Metrics Pipeline dashboard in the Grafana UI includes Syslog Agent metrics.

[Known Issue Fix] The smoke test for Prometheus VMs no longer runs before the Prometheus VM is ready. For more information about this known issue, see Prometheus Smoke Test Fails as Healthwatch Re-Deploys below.

[Known Issue Fix] The Prometheus instance no longer fails to clean up the chunks_head directory. For more information about this known issue, see Prometheus Clean-Up Failure Leads to Full Disk below.

Healthwatch for VMware Tanzu 2.2

[Known Issue Fix] The backup scripts for Prometheus VMs clean up the intermediary snapshots created by BOSH Backup and Restore (BBR). For more information about this known issue, see BBR Backup Snapshots Fill Disk Space on Prometheus VMs below.

[Known Issue] The RabbitMQ dashboards in the Grafana UI show no data for RabbitMQ on- demand instances that are configured to communicate over TLS. For more information about this known issue, see No Data on RabbitMQ Dashboards for RabbitMQ On-Demand Instances Using TLS below.

Healthwatch v2.2.1 uses the following open-source component versions:

Release Date: January 25, 2022
