monitoring

问题 I am writing a test app to monitor another windows application(s) and perform operations before the user is allowed to use them. Background We have users that can access computers and launch applications. For some of these applications, we want the user to fill a little form and then they would be allowed to use the application. At the same time, we want to keep track of the total run time of the application (i.e. how long the user has used the application). The application that a user can

问题 I'm trying to make a sort of task manager -esque program using PerformanceMonitor and a chart. The CPU usage value is thrown onto a label and the chart, obviously, graphs it all out. Problem is PerformanceMonitor only reports the CPU being at nothing or full, but the graph shows lots of little spikes in between, usually not matching the Windows Task Manager graph output. I need to know how I can get PerformanceMonitor , or a similar C# product, to output viable, consistent, and accurate

问题 I have alerts setup on Prometheus where there are different jobs in the alert.I want to find how many times the alert was fired over last week, given the job name.So there is a alerts name "A" and there are multiple jobs "B","C","D" under that, I want to know how many times alert "A" was fired for job "B" in last week. If I use following expression : sum by(alertname) (changes(ALERTS_FOR_STATE[1w])) It gives me total alerts fired in last week but since there are multiple jobs in that, I am

问题 I am not able to export "type=connector-metrics" metrics for Confluent connect service but other metrics are working fine. I am using prometheus exporter java agent to expose metrics from Confluent connect as shown below. Confluent Connect Configuration (/usr/bin/connect-distributed) export KAFKA_OPTS='-javaagent:/opt/prometheus/jmx_prometheus_javaagent-0.12.0.jar=8093:/opt/prometheus/kafka-connect.yml' kafka-connect.yml - pattern: kafka.connect<type=connector-metrics, connector=(.+)><>([a-z-

问题 We are running the node-exporter in containers. To quickly identify on which host each node-exporter is running, I created a metric that looks like this: host{host="$HOSTNAME",node="$CONTAINER_ID"} 1 I'm looking for a way to extract the hostname in host= and create a label for each node-exporter instance as a hostname label. I tried numerous configurations and none seem to work. Current prometheus config looks like this: scrape_configs: - job_name: 'node' scrape_interval: 10s scrape_timeout:

问题 I am monitoring an external device that outputs a boolean value of False when the condition is not met, and a boolean value of True when the condition is met. The problem is, the boolean value is output more than once after the condition is met. This is what the output looks like: False False False False True True False False False So what I would like to be able to do is monitor this value and execute a simple function, only once for each time the boolean changes from False to True. I have

问题 I monitor the execution of an Azure function using the Live Metrics Stream management UI as seen below: Some of these metrics can be retrieved through the Application Insights REST API. However, metrics concerning overall health data, or Servers data, return a null value. For example,the performanceCounters/processCpuPercentage endpoint produces the following output when probed: HTTP/1.1 200 content-type: application/json; charset=utf-8 { "value": { "start": "2018-10-16T11:20:37.366Z", "end":

问题 How to trace all events for service firebird server with delphi xe10? This is my code: my := TIBControlService.Create(Self); my.ServerName := '127.0.0.1/3050'; my.Protocol := TProtocol.TCP; my.LoginPrompt := false; my.TraceFlags := [tfQPrepare, tfQExecute, tfQFetch, tfError, tfStmt, tfConnect, tfTransact, tfBlob, tfService, tfMisc]; my.Params.Add( 'user_name=SYSDBA' ); my.Params.Add( 'password=masterkey' ); // ----- mh := MonitorHook; mh.TraceFlags := my.TraceFlags; Self.IBSQLMonitor1

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.
