# APM v2 isn't showing my data

When an entity or a metric you expect isn't there, work from the symptom you see. Each row below maps a symptom to its most likely cause and the fix.

| Symptom                                          | Likely cause                                                                                                                                                        | Fix                                                                                                                                                                                                          |

| No entities at all                               | The Collector isn't running, or it exports to the wrong region endpoint.                                                                                            | Check the Collector's exporter logs, and confirm the [region endpoint](https://coralogix.com/docs/user-guides/apm-v2/getting-started/apm-onboarding-tutorial.md).                                            |

| An entity shows as Unmonitored                   | Every health policy for it is disabled, so none is evaluating.                                                                                                      | Enable a policy on the entity's **Health** tab.

| An entity shows as N/A                           | Its policies are enabled, but none has data in the selected time range or environment, for example an inactive service or an environment it doesn't send data from. | Check that the service is sending spans, logs, or metrics for that environment and time range.

| Everything is present, but APM v2 is unavailable | The account isn't sending compact span metrics on services and databases.                                                                                           | Migrate - see [Using compact Span Metrics](https://coralogix.com/docs/user-guides/apm-v2/getting-started/using-compact-span-metric.md).                                                                      |

## Still stuck?

If data is flowing but a specific tab stays empty, open the entity's drilldown - a tab with no data names the signal it needs and links to its setup. For anything else, contact <support@coralogix.com>.
