# Troubleshooting
## Service Ping Payload drop
### Symptoms
You will be alerted by a [Sisense alert](https://app.periscopedata.com/app/gitlab/alert/Service-ping-payload-drop-Alert/5a5b8766b8af43b4a75d6e9c684a365f/edit) that is sent to `#g_product_intelligence` Slack channel
### Locating the problem
First you need to identify at which stage in Service Ping data pipeline the drop is occurring.
Start at [Service Ping Health Dashboard](https://app.periscopedata.com/app/gitlab/968489/Product-Intelligence---Service-Ping-Health) on Sisense.
The alert compares the current daily value with the daily value from previous week, excluding the last 48 hours as this is the interval where we export the data in GCP and get it into DWH.
You can use [this query](https://gitlab.com/gitlab-org/gitlab/-/issues/347298#note_836685350) as an example, to start detecting when the drop started.
### Troubleshoot the GitLab application layer
For results about an investigation conducted into an unexpected drop in Service ping Payload events volume, see [this issue](https://gitlab.com/gitlab-data/analytics/-/issues/11071).
### Troubleshoot the data warehouse layer
Reach out to the [Data team](https://about.gitlab.com/handbook/business-technology/data-team/) to ask about current state of data warehouse. On their handbook page there is a [section with contact details](https://about.gitlab.com/handbook/business-technology/data-team/#how-to-connect-with-us).
### Cannot disable Service Ping with the configuration file
The method to disable Service Ping with the GitLab configuration file does not work in
GitLab versions 9.3.0 to 13.12.3. To disable it, you must use the Admin Area in
the GitLab UI instead. For more information, see
[this issue](https://gitlab.com/gitlab-org/gitlab/-/issues/333269).
GitLab functionality and application settings cannot override or circumvent
restrictions at the network layer. If Service Ping is blocked by your firewall,
you are not impacted by this bug.
#### Check if you are affected
You can check if you were affected by this bug by using the Admin Area or by
checking the configuration file of your GitLab instance:
- Using the Admin Area:
1. On the top bar, select **Menu > Admin**.
1. On the left sidebar, select **Settings > Metrics and profiling**.
1. Expand **Usage Statistics**.
1. Are you able to check or uncheck the checkbox to disable Service Ping?
- If _yes_, your GitLab instance is not affected by this bug.
- If you can't check or uncheck the checkbox, you are affected by this bug.
See the steps on [how to fix this](#how-to-fix-the-cannot-disable-service-ping-bug).
- Checking your GitLab instance configuration file:
To check whether you're impacted by this bug, check your instance configuration
settings. The configuration file in which Service Ping can be disabled depends
on your installation and deployment method, but is typically one of the following:
- `/etc/gitlab/gitlab.rb` for Omnibus GitLab Linux Package and Docker.
- `charts.yaml` for GitLab Helm and cloud-native Kubernetes deployments.
- `gitlab.yml` for GitLab installations from source.
To check the relevant configuration file for strings that indicate whether
Service Ping is disabled, you can use `grep`:
```shell
# Linux package
grep "usage_ping_enabled'\] = false" /etc/gitlab/gitlab.rb
# Kubernetes charts
grep "enableUsagePing: false" values.yaml
# From source
grep "usage_ping_enabled'\] = false" gitlab/config.yml
```
If you see any output after running the relevant command, your GitLab instance
may be affected by the bug. Otherwise, your instance is not affected.
#### How to fix the "Cannot disable Service Ping" bug
To work around this bug, you have two options:
- [Update](../../update/index.md) to GitLab 13.12.4 or newer to fix this bug.
- If you can't update to GitLab 13.12.4 or newer, enable Service Ping in the
configuration file, then disable Service Ping in the UI. For example, if you're
using the Linux package:
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['usage_ping_enabled'] = true
```
1. Reconfigure GitLab:
```shell
sudo gitlab-ctl reconfigure
```
1. In GitLab, on the top bar, select **Menu > Admin**.
1. On the left sidebar, select **Settings > Metrics and profiling**.
1. Expand **Usage Statistics**.
1. Clear the **Enable Service Ping** checkbox.
1. Select **Save Changes**.
