+## Push metrics
+
+All the VictoriaMetrics apps support pushing their metrics exposed at `/metrics` page to remote storage in Prometheus text exposition format. This can be done by specifying the following command-line flags:
+
+* `-pushmetrics.url` - the url to push metrics to. For example, `-pushmetrics.url=http://victoria-metrics:8428/api/v1/import/prometheus` instructs to push internal metrics to `/api/v1/import/prometheus` endpoint according to [these docs](#how-to-import-data-in-prometheus-exposition-format). The `-pushmetrics.url` can be specified multiple times. In this case metrics are pushed to all the specified urls. The url can contain basic auth params in the form http://user:pass@hostname/api/v1/import/prometheus .
+* `-pushmetrics.interval` - the interval between pushes. By default it is set to 10 seconds.
+* `-pushmetrics.extraLabel` - label to add to all the metrics before sending them to `-pushmetrics.url`. The label must be specified in the format `label="value"`. It is OK to specify multiple `-pushmetrics.extraLabel` command-line flags. In this case all the specified labels are added to all the metrics sending them to `-pushmetrics.url`.
+
+For example, the following command instructs VictoriaMetrics to push metrics from `/metrics` page to `https://maas.victoriametrics.com/api/v1/import/prometheus` with `user:pass` [Basic auth](https://en.wikipedia.org/wiki/Basic_access_authentication). The `instance="foobar"` and `job="vm"` labels are added to all the metrics before sending them to the remote storage:
+
+```console
+/path/to/victoria-metrics -pushmetrics.url=https://user:pass@maas.victoriametrics.com/api/v1/import/prometheus -pushmetrics.extraLabel='instance="foobar",job="vm"'
+```
+
 ## Cache removal
 
 VictoriaMetrics uses various internal caches. These caches are stored to `<-storageDataPath>/cache` directory during graceful shutdown (e.g. when VictoriaMetrics is stopped by sending `SIGINT` signal). The caches are read on the next VictoriaMetrics startup. Sometimes it is needed to remove such caches on the next startup. This can be performed by placing `reset_cache_on_startup` file inside the `<-storageDataPath>/cache` directory before the restart of VictoriaMetrics. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1447) for details.

For example, `q1 or q2`, `aggr_func(q1) <op> q2`, `q1 <op> aggr_func(q1)`. This may improve query performance if VictoriaMetrics has enough free resources for parallel processing of both sides of the operation.

+* FEATURE: [vmauth](https://docs.victoriametrics.com/vmagent.html): allow duplicate username records with different passwords at configuration file. It should allow password rotation without username change.
+* FEATURE: add ability to push internal metrics (e.g. metrics exposed at `/metrics` page) to the configured remote storage from all the VictoriaMetrics components. See [these docs](https://docs.victoriametrics.com/#push-metrics).

 **Update note 3:** this release introduces backwards-incompatible changes to communication protocol between `vmselect` and `vmstorage` nodes in cluster version of VictoriaMetrics because of added ability to query `vmselect` data from other `vmselect` nodes - see [these docs](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#multi-level-cluster-setup), so read requests to `vmselect` will fail until the upgrade is complete. These errors will stop after all the `vmselect` and `vmstorage` nodes are updated to the new release. It is safe to downgrade to previous releases at any time.

This deprecated param was replaced with [params](https://docs.victoriametrics.com/vmalert.html#url-params).
+
+**Update note 5:** this release changes naming for published linux binaries at [releases](https://github.com/VictoriaMetrics/VictoriaMetrics/releases). Now names for binaries for all the supported platforms match the following template - `$(APP_NAME)-$(GOOS)-$(GOARCH)-$(VERSION).tar.gz`. For example, `victoria-metrics-linux-amd64-v1.79.0.tar.gz`. Previously linux binaries didn't have `$(GOOS)` part, e.g. they had the name `victoria-metrics-amd64-v1.79.0.tar.gz`. Please update automation scripts for upgrading VictoriaMetrics releases according to this change.

It allows discovering Virtual Machines at [Azure Cloud](https://azure.microsoft.com/en-us/). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1364).

+## Push metrics
+
+All the VictoriaMetrics apps support pushing their metrics exposed at `/metrics` page to remote storage in Prometheus text exposition format. This can be done by specifying the following command-line flags:
+
+* `-pushmetrics.url` - the url to push metrics to. For example, `-pushmetrics.url=http://victoria-metrics:8428/api/v1/import/prometheus` instructs to push internal metrics to `/api/v1/import/prometheus` endpoint according to [these docs](#how-to-import-data-in-prometheus-exposition-format). The `-pushmetrics.url` can be specified multiple times. In this case metrics are pushed to all the specified urls. The url can contain basic auth params in the form http://user:pass@hostname/api/v1/import/prometheus .
+* `-pushmetrics.interval` - the interval between pushes. By default it is set to 10 seconds.
+* `-pushmetrics.extraLabel` - label to add to all the metrics before sending them to `-pushmetrics.url`. The label must be specified in the format `label="value"`. It is OK to specify multiple `-pushmetrics.extraLabel` command-line flags. In this case all the specified labels are added to all the metrics sending them to `-pushmetrics.url`.
+
+For example, the following command instructs VictoriaMetrics to push metrics from `/metrics` page to `https://maas.victoriametrics.com/api/v1/import/prometheus` with `user:pass` [Basic auth](https://en.wikipedia.org/wiki/Basic_access_authentication). The `instance="foobar"` and `job="vm"` labels are added to all the metrics before sending them to the remote storage:
+
+```console

 ## Cache removal
 
 VictoriaMetrics uses various internal caches. These caches are stored to `<-storageDataPath>/cache` directory during graceful shutdown (e.g. when VictoriaMetrics is stopped by sending `SIGINT` signal). The caches are read on the next VictoriaMetrics startup. Sometimes it is needed to remove such caches on the next startup. This can be performed by placing `reset_cache_on_startup` file inside the `<-storageDataPath>/cache` directory before the restart of VictoriaMetrics.

+## Push metrics
+
+All the VictoriaMetrics apps support pushing their metrics exposed at `/metrics` page to remote storage in Prometheus text exposition format. This can be done by specifying the following command-line flags:
+
+* `-pushmetrics.url` - the url to push metrics to. For example, `-pushmetrics.url=http://victoria-metrics:8428/api/v1/import/prometheus` instructs to push internal metrics to `/api/v1/import/prometheus` endpoint according to [these docs](#how-to-import-data-in-prometheus-exposition-format). The `-pushmetrics.url` can be specified multiple times. In this case metrics are pushed to all the specified urls. The url can contain basic auth params in the form http://user:pass@hostname/api/v1/import/prometheus .
+* `-pushmetrics.interval` - the interval between pushes. By default it is set to 10 seconds.
+* `-pushmetrics.extraLabel` - label to add to all the metrics before sending them to `-pushmetrics.url`. The label must be specified in the format `label="value"`. It is OK to specify multiple `-pushmetrics.extraLabel` command-line flags. In this case all the specified labels are added to all the metrics sending them to `-pushmetrics.url`.
+
+For example, the following command instructs VictoriaMetrics to push metrics from `/metrics` page to `https://maas.victoriametrics.com/api/v1/import/prometheus` with `user:pass` [Basic auth](https://en.wikipedia.org/wiki/Basic_access_authentication). The `instance="foobar"` and `job="vm"` labels are added to all the metrics before sending them to the remote storage:
+
+```console

 ## Cache removal
 
 VictoriaMetrics uses various internal caches. These caches are stored to `<-storageDataPath>/cache` directory during graceful shutdown (e.g. when VictoriaMetrics is stopped by sending `SIGINT` signal). The caches are read on the next VictoriaMetrics startup. Sometimes it is needed to remove such caches on the next startup. This can be performed by placing `reset_cache_on_startup` file inside the `<-storageDataPath>/cache` directory before the restart of VictoriaMetrics.
