![]() fluentd prometheus exporter ( ) - works but looks like I can extract only very simple metrics and I cannot make any advanced regexp analysis of a line(s) from log fileĭoes any one here has a really running solution for monitoring advanced metrics from log files using "some exporter" + Prometheus + Grafana? Or instead of exporter some program from which I could grab results using Prometheus push gateway.grok_exporter ( ) - works but I can extract only limited information + one instance can monitor only one log file which mean I would have to start more instances exporting on more ports and configure all off them in prometheus - which makes too many new points of failure.mtail ( ) - works but existing version cannot easily monitor more files - in general it cannot bind specific mtail program (receipt for analysis) to some specific log file + I cannot easily add log file name into tag.Also alerting in new Grafana 4.x works very well.īut I have quite a problem to find suitable exporter/ program which could analyze log files "on fly" and extract metrics from them. Prometheus + Grafana are OK I already use them a lot with different exporters like node_exporter or mysql_exporter etc. The JMX exporter can export from a wide variety of JVM-based applications, for example Kafka and Cassandra. And I need to grab corresponding metrics using Prometheus and show in Grafana + set some alerting on it. The exporter default port wiki page has become another catalog of exporters, and may include exporters not listed here due to overlapping functionality or still being in development. Using an InstallerPath parameter in the PowerShell script allowed us to specify the path to the current (internally preferred) stable version, but also allow people to specify a different installer version/path at run time.I need to monitor very different log files for errors, success status etc. System metrics of machines can be exported with Node exporter or Windows exporter. Since the current and all previous versions of the exporter are included in the GitHub repo, we opted to download the installer at runtime. Prometheus exporter for Windows machines (by prometheus-community).The firewall exception was scoped to our local Prometheus server using the Get-NetFirewallRule and Set-NetFirewallAddressFilter PowerShell commandlets. ![]() ![]() The service auto-start problem was resolved by extending the restart period to 5 minutes.Resolving the UAC prompt was accomplished by using an Invoke-Command script block to remotely start msiexec.exe on the Windows server using Start-Process with the ‘-Verb RunAs’.And the last issue was deciding how/where to stage the installer, so it could be run on the servers. Typically this occurs when the reboot is part of the monthly patching process. Another problem, that we discovered during testing, was that the windows_exporter service occasionally fails to auto-start after the server has been rebooted. The second issue was scoping the exporter’s firewall rule (no IP restrictions by default). The first issue was the UAC prompt when executing the msi remotely. Using a PowerShell script to automate the (remote) installation of the exporter encountered a few minor issues. MSSQL on a server without SQL Server installed) will result in errors being logged to the Application event log each time the collector is initiated (ie. Note: installing unnecessary collectors (eg. IIS, MSSQL, Exchange, Active Directory, etc.). This parameter specifies which metric collections are enabled (eg. Of the supported parameters, ENABLED_COLLECTORS is the one that most people will need. The exporter’s msi installer is very simple (supports 7 parameters) and will only take a few seconds to complete. The exporter is free to use under an MIT license and supports an extensive list of WMI metrics that are grouped into Collectors. We ultimately decided to use the windows_exporter agent available in the Prometheus Community on GitHub. One of the obstacles to implementing Prometheus monitoring on our Windows servers was finding and installing an agent. (I’ll post a writeup about Prometheus in the future) More recently, we began using it for our Windows-based servers too. Prometheus is an open-source monitoring solution that our Linux team has been using for several years.
