Use data routing to keep, archive, or discard your metrics 🔗
Use data routing to choose how to ingest and store all the metric time series (MTS) that have the same metric. Routing options include to keep metrics in real-time, archive them, or drop them altogether.
Routing exception rules let you modify the behavior of data routing. See Use routing exception rules to route a specific MTS or restore archived data.
Use data routing rules to define how to store your metrics 🔗
注釈
All roles can view data routing. You must have the admin user role to edit default routing. For more information, see Splunk Observability Cloud のロールについて.
Routing rule options 🔗
You have the following options to route your MTS:
Ingest and keep metrics real-time (default). Metrics stored in the real-time tier are available in charts and detectors.
Send your data to archived metrics. Archived metrics are not available in charts and detectors. You can change routing to real time or filter a subset of data to real time to make those metrics available in charts and detectors again. You can restore archived data from up to 8 days ago in case you need it.
Drop your metrics. If you select this option, metrics are dropped and aren’t available for monitoring. You can still keep aggregated MTS derived from those metrics.
注釈
You cannot archive histogram metrics.
Edit the routing rule for a metric 🔗
To edit the routing rules for a metric and its MTS, follow these steps:
Access your Splunk Observability Cloud account.
In the left navigation menu, select Settings > Metrics Pipeline Management to access the landing screen with a list of all your metrics and a summary of their rulesets.
Select or search for a metric to access the metric’s summary page.
From a metric’s summary screen, select Edit next to the Ingestion tile.
In the Update data routing dialog, select the radio button next to the new routing option you want to set.
システムはメトリクスのサマリーページに戻ります。ページの上部には、更新に関する通知が表示されます：
更新が成功した場合、通知は緑色でハイライトされます。テキストはメトリクスのルーティングが更新されたことを確認します。
更新が適用されなかった場合、通知は赤で強調表示されます。テキストには、更新が適用されなかった理由が表示されます。
Use routing exception rules to route a specific MTS or restore archived data 🔗
注釈
You must have the admin or power user role to create or edit an exception rule. For more information, see Splunk Observability Cloud のロールについて.
Use routing exception rules to override archiving selected metrics and their associated MTS.
Routing exception rules allow you to:
Change the destination for an MTS.
Restore historical archived MTS to real-time storage. You can restore up to 8 days of archived data.
Note that if you create different routing exception rules with the same filters, MPM will not duplicate any MTS. If you decide to send those MTS to real time monitoring, MPM only restores the data points for those MTS once.
Routing exception rule options 🔗
Routing exception rules have the following options:
フィールド |
説明 |
必須ですか？ |
|---|---|---|
Rule name and description |
Custom name for the new routing exception rule. |
あり |
Filter MTS population for real-time monitoring |
Metrics pipeline management routes the population of MTS that match these dimensions to real time instead of archiving them. |
あり |
Restore archived MTS from filtered population |
The time period before the current time where you want to restore historical archived MTS to real-time storage. When you add or reactivate a rule, if you make any changes to the dimensions, you can set a new restoration window. |
なし |
ルーティング例外ルールを追加する 🔗
メトリクスに関連付けられたMTSのデフォルトルーティングをオーバーライドするルーティング例外ルールを追加します。
To add the rule, follow these steps:
Access your Splunk Observability Cloud account.
In the left navigation menu, select Settings > Metrics Pipeline Management to access the landing screen with a list of all your metrics and a summary of their rulesets.
Select or search for a metric to access the metric’s summary page.
From a metric’s summary screen, select Add (+) icon in the Routing exceptions tile.
In the Create routing exception rule dialog, complete the options. See Routing exception rule options.
The system returns to the summary page for the metric. Check the status column to verify the routing exception has been added successfully.
ルーティング例外ルールを編集する 🔗
注釈
To change the restoration time period, deactivate the routing exception rule, and then reactivate it and choose a new time window.
既存のルーティング例外ルールを編集するには、以下の手順を実行します：
Access your Splunk Observability Cloud account.
In the left navigation menu, select Settings > Metrics Pipeline Management to access the landing screen with a list of all your metrics and a summary of their rulesets.
Select or search for a metric to access the metric’s summary page.
From the list of rules, find the one you want to change, then select Edit in the More actions (⋮) menu.
In the dialog, update the routing exception settings you want to change, and select Update. See Routing exception rule options.
Activate or deactivate a routing exception rule 🔗
注意
Activating a routing exception rule might move archived MTS to real-time storage and your usage will most likely increase.
Deactivating a routing exception rule makes real-time data for those MTS unavailable. Historical data already routed to real-time metrics is not modified and stays in charts.
To activate or deactivate a routing exception rule, follow these steps:
Access your Splunk Observability Cloud account.
In the left navigation menu, select Settings > Metrics Pipeline Management to access the landing screen with a list of all your metrics and a summary of their rulesets.
Select or search for a metric to access the metric’s summary page.
ルールのリストで、ルールを見つけます。非アクティブ化されている場合、そのステータスは Inactive です。
In the More actions (⋮) menu, select Activate or Deactivate, and confirm.
If activating the exception rule moves MTS from archived to real-time storage, metrics
The dialog also lets you choose the amount of historical archived MTS to restore.
ルーティング例外ルールを削除する 🔗
注意
When you delete a routing exception rule, the related MTS are no longer routed to real-time metrics. As a result, charts and detectors that depend on the MTS stop working.
ルーティング例外ルールを削除するには、以下の手順に従います：
Access your Splunk Observability Cloud account.
In the left navigation menu, select Settings > Metrics Pipeline Management to access the landing screen with a list of all your metrics and a summary of their rulesets.
Select or search for a metric to access the metric’s summary page.
In the list of rules, find the rule you want to delete.
In the More actions (⋮) menu, select Delete and confirm.
Extrapolate data in charts and dashboards 🔗
During and after restoring data, you might see horizontal lines going across the empty part of the chart and connecting data points. The straight lines on the chart are an extrapolation that connects 2 existing data points. They correspond to the archived data that was not restored because they were not included in the exception rule.
You can set the extrapolation policy in the Configure Plot setting to either Last Value or Zero, which changes the straight lines into a horizontal 1 or 0.
