Responding to monitoring alerts

an alert has fired this page covers what to do next deciding whether it is actionable, tuning it if it is noisy, and interpreting the alert message two monitoring paths exist, and the response differs standard monitoring via the factry historian portal, auto configured per installation custom monitoring via your own grafana alerting, for implementation specific checks such as recalculations work through the section that matches the alert you received this page is about responding to alerts for the factry historian portal, setting up alerts, creating notification channels and assigning recipients is covered in managing alerts & notifications docid\ xocacmxp7iiyvoyptg32d portal roles, and who may acknowledge or silence an alert, are covered in managing users docid 5z5iefc9gpfya92qp1h46 factry historian portal alerts is the alert actionable? rule out the two most common non issues first many alerts at once, especially across one site this is almost always a single shared cause the site's pcs or gateways are offline, or the vpn is down, so every collector alerts together restore the connection and the alerts clear together a known false positive check the table below before investigating further acknowledging is not a fix, and it does not last an acknowledgement holds only while the alert stays active as soon as the alert returns to normal and fires again, you are notified again a silence lasts 7 days at most for a condition that will keep coming back, such as a collector service that is deliberately stopped, pause the collector instead common false positives alert what it usually means action collecting insufficient points data arrives in bursts, not continuously (sql, csv, sap and batch collectors) the alert is added automatically on install increase the activation delay, or do not attach this alert to email collector health / last seen the collector service is stopped on purpose, or the collector has not been connected yet pause the collector and leave it paused until the connection is set up acknowledging is not enough it holds only while the alert is active, and a silence expires after 7 days license expiry < 30 days informational only confirm the actual expiry date alerts that usually need action alert what it usually means action disk space above threshold the drive is genuinely filling up free space on the machine or allocate more disk space on customer hosted servers that factry cannot reach, the customer has to act memory or cpu above threshold a process is consuming more than the default allows find the process if that level is normal for this machine, ask factry to raise the threshold instead of chasing it every time if the level is not normal for the machine, investigate the issue and troubleshoot collector health / last seen the collector should be running but is down or unreachable check the pc, the gateway and the vpn, then restart the collector service collecting insufficient points a collector that normally streams continuously has slowed down or stopped check the source system and the collector configuration license expiry the license really is close to expiring contact factry to renew before the date tuning a noisy alert alerts created automatically by the factry historian portal can only be edited by factry you can see the current threshold and activation delay, but not change them two options ask factry to adjust the threshold or the activation delay on the automatic alert create your own alert with your own threshold, and link it to the notification channel instead adjustments that come up repeatedly raise the threshold when a resource sits stably above the default memory on a shared collector pc is often normal at 90% or 95% increase the activation delay for bursty collectors, so short gaps do not trigger silence during planned maintenance, then lift the silence as soon as the work is done see managing alerts & notifications a portal silence lasts 7 days at most maintenance that runs longer has to be re silenced an alert fires but nobody is notified not every alert is linked to a notification channel by default if an alert appears on the overview page but no email arrives, check the link between the alert and the channel first see managing alerts & notifications docid\ xocacmxp7iiyvoyptg32d custom grafana alerts common false positives alert what it usually means action no data, although the measurement has values the rule filters on status = good a stopped collection or a bad status leaves no good data behind, so the rule fires even though the historian still shows values (bad status) check the measurement status in the historian iif a no data gap should not alert, change the rule's no data handling for example choose normal or keep the last state rapid switching between alerting and normal an alert rule execution error, for example the grafana database file was briefly locked check the grafana logs usually transient tuning a noisy alert custom rules are yours to edit, so tuning does not go through factry raise the threshold when the measured value sits stably above the default increase the pending period so short excursions do not trigger set the no data handling deliberately per rule alerting, normal, or keep the last state checking notification delivery connect the alert directly to a contact point that covers almost every case one alert routes to one contact point if you need several delivery types, for example email and slack, put them all inside that single contact point routing one alert to several contact points is possible with notification policies that is advanced use, and the setup differs between grafana versions, so follow the grafana alerting documentation for the version you run customising the alert message edit the text under contact points > templates tab , not under the alertmanager section the template only takes effect once it is selected in the contact point settings to point the alert back at its panel, add the dashboard uid and panel id under "add details for your alert" this produces a link, not a graph use {{ panelurl }} in the template for a clickable link to deliver to microsoft teams, create a " post to a channel when a webhook request is received " workflow and use the webhook url it returns showing an actual graph image inside the alert message requires the grafana image renderer service ask factry to set this up grafana's alerting interface changes between versions check the grafana alerting documentation https //grafana com/docs/grafana/latest/alerting/ for the version you are running before following the steps above related pages managing alerts & notifications docid\ xocacmxp7iiyvoyptg32d managing users docid
