Adam Moussa 6c34bf7e66 feat(syslog-server): IaC-managed EC2 StatusCheckFailed alarm + auto-recovery (INFRA-58) (#4) ... Add a CloudFormation-managed EC2 status-check alarm for the live syslog instance, replacing the orphaned EC2-StatusCheck-syslog-server alarm that still points at the terminated i-0a7470914f0151b97. The instance is a CFN resource in this stack, so both alarms dimension on instance.instanceId (Ref) rather than a literal id — they follow the instance across future replacements (e.g. userDataCausesReplacement). - EC2-StatusCheck-syslog-server: combined StatusCheckFailed, Maximum >= 1, 300s period, 2 eval periods, treatMissingData=breaching, SNS -> site-alerts. Mirrors the existing Syslog-NoIncomingLogs SNS reference. - EC2-StatusCheckSystem-syslog-server-recover: StatusCheckFailed_System with an EC2 recover action (+ SNS). AWS only allows RECOVER on the _System metric, not the combined metric, so it is a separate alarm; treatMissingData=notBreaching per AWS recovery-alarm guidance. Validated with tsc, cdk synth, cfn-lint (W2001 bootstrap warning only). The pre-existing orphaned alarm is deleted separately, not here.		2026-06-17 15:02:04 -04:00
