monitoring

问题 We need to add results of two queries in Prometheus. Snippet is below: (probe_ssl_earliest_cert_expiry{job="SSL-expiry"} - time() < 86400 * 738 )*1000 + (node_time_seconds*1000) but the result says no data as shown below: 回答1: You will get an empty result if the metrics do not match. The reason is that for binary operator vector1 <op> vector2 vector1 and vector2 results in a vector consisting of the elements of vector1 for which there are elements in vector2 with exactly matching label sets.

问题 Is there a way to monitor the pod status and restart count of pods running in a GKE cluster with Stackdriver? While I can see CPU, memory and disk usage metrics for all pods in Stackdriver there seems to be no way of getting metrics about crashing pods or pods in a replica set being restarted due to crashes. I'm using a Kubernetes replica set to manage the pods, hence they are respawned and created with a new name when they crash. As far as I can tell the metrics in Stackdriver appear by pod

问题 I’m struggling to create a chart with stackdriver monitoring with a log-based metric. My metric is a counter one with no unit by default. Logs are available for my log-based metric but when I create a chart with my metric, it says no data is available for the... . Here’s my metric which does work (called isOperatorAllowed): resource.type="container" resource.labels.namespace_id="default" jsonPayload.message="CaseForOperator flags" logName="projects/PROJECT-ID/logs/app" jsonPayload

问题 I have a kafka setup that includes a jmx exporter to prometheus. I'm looking for a metric, that gives the offset lag based on topic and groupid. I'm running kafka 2.2.0. Some resources online point to a metric called kafka.consumer , but I have no such metric in my setup. From my jmxterminal: $>domains #following domains are available JMImplementation com.sun.management java.lang java.nio java.util.logging jdk.management.jfr kafka kafka.cluster kafka.controller kafka.coordinator.group kafka

问题 I have an elasticsearch instance that receives logs from multiple backup routines. I'd like to query ES for these logs from Grafana and set up a panel that shows the last time for the different backups. Ideally I would also like to be able to show this in color if the time is longer than a certain threshold. Basically the idea is to have a display that shows, for instance, green if a certain backup has been completed in the last 24 hours, and red if it hasn't. How would I do this in Grafana
