feature: [vmagent] Add service discovery support for Vultr (#6068)
### Describe Your Changes related issue: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6041 #### Added - Added service discovery support for Vultr. #### Docs - `CHANGELOG.md`, `sd_configs.md`, `vmagent.md` are updated. #### Note - Useful links: - Vultr API: https://www.vultr.com/api/#tag/instances/operation/list-instances - Vultr client SDK: https://github.com/vultr/govultr - Prometheus SD: https://github.com/prometheus/prometheus/tree/main/discovery/vultr --- ### Checklist The following checks are mandatory: - [X] I have read the [Contributing Guidelines](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/CONTRIBUTING.md) - [x] All commits are signed and include `Signed-off-by` line. Use `git commit -s` to include `Signed-off-by` your commits. See this [doc](https://git-scm.com/book/en/v2/Git-Tools-Signing-Your-Work) about how to sign your commits. - [x] Tests are passing locally. Use `make test` to run all tests locally. - [x] Linting is passing locally. Use `make check-all` to run all linters locally. Further checks are optional for External Contributions: - [X] Include a link to the GitHub issue in the commit message, if issue exists. - [x] Mention the change in the [Changelog](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/CHANGELOG.md). Explain what has changed and why. If there is a related issue or documentation change - link them as well. Tips for writing a good changelog message:: * Write a human-readable changelog message that describes the problem and solution. * Include a link to the issue or pull request in your changelog message. * Use specific language identifying the fix, such as an error message, metric name, or flag name. * Provide a link to the relevant documentation for any new features you add or modify. - [ ] After your pull request is merged, please add a message to the issue with instructions for how to test the fix or try the feature you added. Here is an [example](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4048#issuecomment-1546453726) - [x] Do not close the original issue before the change is released. Please note, in some cases Github can automatically close the issue once PR is merged. Re-open the issue in such case. - [x] If the change somehow affects public interfaces (a new flag was added or updated, or some behavior has changed) - add the corresponding change to documentation.

* FEATURE: [dashboards/single](https://grafana.com/grafana/dashboards/10229): add `Network Usage` panel to `Resource Usage` row.
|
||||
* FEATURE: [dashboards/operator](https://grafana.com/grafana/dashboards/17869), [dashboards/backupmanager](https://grafana.com/grafana/dashboards/17798) and [dashboard/tenant-statistic](https://grafana.com/grafana/dashboards/16399): update dashboard to be compatible with Grafana 10+ version.
|
||||
* FEATURE: [dashboards/cluster](https://grafana.com/grafana/dashboards/11176): add new panel `Concurrent selects` to `vmstorage` row. The panel will show how many ongoing select queries are processed by vmstorage and should help to identify resource bottlenecks. See panel description for more details.
|
||||
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add service discovery support for [Vultr](https://www.vultr.com/). See [these docs](https://docs.victoriametrics.com/sd_configs/#vultr_sd_configs) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6041).
|

|
||||
* BUGFIX: [vmui](https://docs.victoriametrics.com/#vmui): fix bug that prevents the first query trace from expanding on click event. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6186). The issue was introduced in [v1.100.0](https://docs.victoriametrics.com/changelog/#v11000) release.
|
||||
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent/): prevent potential panic during [stream aggregation](https://docs.victoriametrics.com/stream-aggregation.html) if more than one `--remoteWrite.streamAggr.dedupInterval` is configured.

|
||||
# Additional HTTP API client options can be specified here.
|

# See https://docs.victoriametrics.com/sd_configs.html#http-api-client-options
|
||||
|
||||

```
|
||||
|

Each discovered target has an [`__address__`](https://docs.victoriametrics.com/relabeling.html#how-to-modify-scrape-urls-in-targets) label set
|
||||
to `<FQDN>:<port>`, where FQDN is discovered instance address and `<port>` is the port from the `vultr_sd_configs` (default port is `80`).
|
||||
|
||||
The following meta labels are available on discovered targets during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):
|
||||
|
||||
* `__meta_vultr_instance_id`: A unique ID for the VPS Instance.
|
||||
* `__meta_vultr_instance_label`: The user-supplied label for this instance.
|
||||
* `__meta_vultr_instance_os`: The [Operating System name](https://www.vultr.com/api/#operation/list-os).
|
||||
* `__meta_vultr_instance_os_id`: The [Operating System id](https://www.vultr.com/api/#operation/list-os) used by this instance.
|
||||
* `__meta_vultr_instance_region`: The [Region id](https://www.vultr.com/api/#operation/list-regions) where the Instance is located.
|
||||
* `__meta_vultr_instance_plan`: A unique ID for the Plan.
|
||||
* `__meta_vultr_instance_main_ip`: The main IPv4 address.
|
||||
* `__meta_vultr_instance_internal_ip`: The internal IP used by this instance, if set. Only relevant when a VPC is attached.
|
||||
* `__meta_vultr_instance_main_ipv6`: The main IPv6 network address.
|
||||
* `__meta_vultr_instance_hostname`: The hostname for this instance.
|
||||
* `__meta_vultr_instance_server_status`: The server health status, which could be `none`, `locked`, `installingbooting`, `ok`.
|
||||
* `__meta_vultr_instance_vcpu_count`: Number of vCPUs.
|
||||
* `__meta_vultr_instance_ram_mb`: The amount of RAM in MB.
|
||||
* `__meta_vultr_instance_allowed_bandwidth_gb`: Monthly bandwidth quota in GB.
|
||||
* `__meta_vultr_instance_disk_gb`: The size of the disk in GB.
|
||||
