Community FAQ

Questions by product

Alertmanager FAQ

How complex is it to self-host Alertmanager alongside Prometheus in a production environment?

Self-hosting Alertmanager requires moderate operational expertise. You need to manage configuration files for routing, grouping, and inhibition rules, handle high availability setups manually (e.g., clustering or multiple instances), and ensure secure access controls. While it integrates seamlessly with Prometheus, there is no built-in UI for alert management, so you must rely on configuration and external tools for incident workflows.

Community insight informed by Reddit discussions

Does Alertmanager support offline alert processing or queueing if the notification endpoints are temporarily unreachable?

Alertmanager does not natively support offline or persistent queueing of alerts. If notification endpoints (like email, Slack, or PagerDuty) are down, Alertmanager will retry sending alerts based on its retry logic, but alerts are kept in memory only. Persistent storage or advanced offline handling requires external tooling or custom integrations.

Community insight informed by Hacker News discussions

Who owns the alert data processed by Alertmanager, and is any data sent to third parties by default?

All alert data processed by Alertmanager remains fully under your control and ownership since it is a self-hosted open-source component. Alertmanager does not send any data to third parties by default; all routing and notifications are configured by you. Data privacy depends on your notification integrations and network security.

Community insight informed by StackOverflow discussions

Are there API limitations when integrating Alertmanager with custom incident management tools?

Alertmanager exposes a REST API primarily for alert ingestion and status querying, but it lacks advanced incident management APIs such as on-call scheduling or collaboration features. Its API is sufficient for basic alert routing and silencing but requires external systems for full incident lifecycle management.

Community insight informed by Forums discussions

What are the recommended methods to migrate or export alert configurations from Alertmanager for backup or transfer?

Alertmanager stores its configuration in YAML files, which can be version-controlled for backup and migration. There is no built-in export/import tool, so migration involves copying and validating these config files in the target environment. For alert history or silences, you may need to export the data from Alertmanager's API or persist it externally, as it is stored in memory or ephemeral storage.

Community insight informed by Reddit discussions

Opsgenie FAQ

Is Opsgenie available for self-hosting or is it fully SaaS only?

Opsgenie is a fully cloud-based SaaS solution provided by Atlassian and does not offer a self-hosted deployment option. All alerting, scheduling, and incident management data is hosted on Atlassian's cloud infrastructure, which means you cannot run Opsgenie on your own servers.

Community insight informed by Reddit discussions

Can Opsgenie function offline or handle incident alerts without internet connectivity?

Opsgenie requires internet connectivity to receive, route, and escalate alerts since it operates as a cloud service. There is no offline mode; if your network is down, alerts will not be processed until connectivity is restored.

Community insight informed by Hacker News discussions

What are the data ownership and export options for incidents and alert history in Opsgenie?

All incident and alert data in Opsgenie is stored in Atlassian's cloud. You can export alert and incident data via the Opsgenie API in JSON or CSV formats for backup or migration purposes. However, there is no built-in tool for full data export or migration to other platforms, so data extraction relies on API usage.

Community insight informed by StackOverflow discussions

Are there any limitations or rate limits on the Opsgenie API for alert management?

Opsgenie's REST API has rate limits to ensure service stability, typically around 60 requests per minute per API key, though exact limits can vary by plan. The API supports creating, updating, and acknowledging alerts, managing schedules, and retrieving incident data, but bulk operations may require batching due to these limits.

Community insight informed by Forums discussions

What is the recommended approach to migrate incident data from Opsgenie to another incident management tool?

Since Opsgenie does not provide a native migration tool, the recommended approach is to use the Opsgenie API to export incident and alert data in JSON or CSV format, then transform and import that data into the target system. This process often requires custom scripting and depends on the destination tool's import capabilities.

Community insight informed by Reddit discussions

PagerDuty FAQ

Is it possible to self-host PagerDuty or run it on-premises for full data control?

PagerDuty is a fully managed SaaS platform and does not offer a self-hosted or on-premises deployment option. All data is processed and stored within PagerDuty's cloud infrastructure, so teams requiring full on-premises control or self-hosting will need to consider alternative incident management solutions.

Community insight informed by Reddit discussions

How does PagerDuty handle offline functionality or incident management when internet connectivity is lost?

PagerDuty relies on cloud connectivity for real-time incident detection, alerting, and escalation. It has very limited offline functionality—users cannot receive or acknowledge alerts without internet access. Teams in environments with unreliable connectivity may experience delays in incident response.

Community insight informed by Hacker News discussions

What are the data export options for migrating away from PagerDuty?

PagerDuty allows exporting incident and alert data via its REST API in JSON format. However, there is no built-in full data export or backup feature for complete account migration. Teams looking to migrate should use the API to extract data and manually migrate configurations and escalation policies.

Community insight informed by StackOverflow discussions

Are there any rate limits or restrictions on PagerDuty's API that impact automation?

Yes, PagerDuty's API enforces rate limits to ensure platform stability. The default limit is 500 requests per minute per account, with burst capacity allowed. Exceeding these limits results in HTTP 429 errors. Automation workflows should implement retry logic and rate limiting to avoid disruptions.

Community insight informed by Forums discussions

Who owns the incident and alert data stored in PagerDuty, and how is data privacy handled?

Customers retain ownership of their incident and alert data stored in PagerDuty. PagerDuty acts as a data processor and complies with industry-standard security and privacy practices, including GDPR. Data is encrypted in transit and at rest, but since it is stored in PagerDuty's cloud, organizations must trust their data handling policies.

Splunk On-Call FAQ

Does Splunk On-Call support self-hosting or is it fully SaaS-only?

Splunk On-Call is offered exclusively as a SaaS platform and does not support self-hosting. All alert routing, escalation policies, and incident workflows are managed through their cloud infrastructure, so organizations must rely on Splunk's hosted environment.

Community insight informed by Reddit discussions

Can Splunk On-Call function offline or handle incident alerts without internet connectivity?

No, Splunk On-Call requires an active internet connection to receive and route alerts, manage schedules, and trigger escalations. There is no offline mode or local agent that can operate independently of the cloud service.

Community insight informed by Hacker News discussions

What are the data ownership and export capabilities of Splunk On-Call for compliance purposes?

Splunk On-Call stores incident and alert data within its cloud environment, and customers retain ownership of their data. The platform provides APIs and UI options to export incident history and on-call schedules in common formats like CSV or JSON for compliance and backup. However, full data export for complete offline archival requires manual extraction via these tools.

Community insight informed by StackOverflow discussions

Are there any notable API limitations when integrating Splunk On-Call with custom monitoring tools?

The Splunk On-Call API supports creating, updating, and querying incidents, schedules, and escalation policies, but it has rate limits that can impact high-frequency alerting workflows. Additionally, some advanced features like complex escalation logic are only configurable via the web UI and not fully exposed through the API.

Community insight informed by Forums discussions

What is the recommended migration or export path if we want to move from Splunk On-Call to another incident management platform?

Currently, Splunk On-Call does not offer automated migration tools. The recommended approach is to use their API or UI export features to extract incident history, schedules, and escalation policies in JSON or CSV formats, then manually import or configure these in the target platform. Planning for data transformation and validation is necessary to ensure continuity.
