Use Opserver to monitor your ASP (third, monitor your server status)

beforewords

There have been 2 articles on how to monitor the ASP. NET Core project.

Today we mainly introduce how to use Opserver to monitor the state of our servers.

The Opserver feature is actually very powerful and he can be used to connect any support bosun, Orion, or direct WMI monitoring data.

The approximate effect is as follows:

Body1. Through the WMI monitoring server that comes with Windows

First, we find the relevant configuration file, modify the configuration file name DashboardSettings.json.example toDashboardSettings.json

then modify Dashboardsettings.json to set the connection address   providers, here we take WMI as an example, as follows:

{  "providers":    {"WMI": {      //  List of nodes to monitor      // (Optional) How long to cache static data (node name, hardware, etc.)-defaults to 5 minutes      // (Optional) How long to cache Dynamic Data (utilizations, etc.)-defaults to seconds      // (Optional) How long to retain data (in memory) – defaults to hours      " Username ":" Administrator "    }}

Explain the parameter description:

• nodesCan have more than one, can fill the server name or IP address
• StaticDataTimeoutSecondsHow long does it take to cache static data (node name, hardware, and so on)-default is 5 minutes
• DynamicDataTimeoutSecondsHow long it takes to cache Dynamic Data (CPU, load time, etc.)-default is 30 seconds
• HistoryHoursThe duration of the record is retained by default of 2 hours
• UsernameThe account name of the remote server
• PasswordThe remote server's password (PS, I am here because the connection is the local machine so it is not necessary.)

After setting up the connection, we can set our alert value as follows:

Set Alert values

Key	explain
cpuWarningPercent	CPU Usage alert (yellow)
cpuCriticalPercent	CPU usage hazard (red)
memoryWarningPercent	Memory usage alert (yellow)
memoryCriticalPercent	Memory usage hazard (red)
diskWarningPercent	Disk space usage alert (yellow)
diskCriticalPercent	Disk space usage hazard (red)

The JSON configuration is added directly under the providers node.

As follows:

{"providers""cpuwarningpercent"  : "cpucriticalpercent": "   Memorywarningpercent ":  " memorycriticalpercent   ":" Diskwarningpercent ":   "diskcriticalpercent":

Multiple servers, the configuration of the server is not necessarily the same, so we need to set the alarm value separately according to the server configuration, we can add the Categories node, and configure the following:

"Categories": [    {     //  Name for this group of servers     "pattern": "-sql",     " Cpuwarningpercent ":",      "cpucriticalpercent": "      memorywarningpercent": 98,      "Memorycriticalpercent" : 99.2 },     "name": "Second set",      "pattern": "-sql",      "cpuwarningpercent":      Cpucriticalpercent ":",      "Memorywarningpercent": 98,     "Memorycriticalpercent": 99.2 }]

In this way, we have completed our use of WMI to gather information and show all the work on Opserver.

Of course, the official recommendation is to use the form of Bosun +scollector+opserver to collect and display

So, let's talk about it below (but I didn't practice it myself.) Limited resources)

2. Monitoring server via Bosun +scollector

1, Bosun Rapid installation (of course, there is no use of Docker. But to tell the truth. It's too complicated. Maybe it's because it's too complicated, just put it in the container and simplify the installation.

• Installing Docker

.. I'm not going to talk about it. Installation steps directly website: https://docs.docker.com/engine/installation/

• Installing Bosun in Docker

Use the command " docker run -d -p 4242:4242 -p 8070:8070 stackexchange/bosun ", install Bosun, file about 200 m, waiting to complete.

• Check if the installation is successful

Visit website http://docker-server-ip:8070, display the Bosun interface, that is, the installation is successful. At this time, the native monitoring data has been collected, you can view the corresponding data.

2. Server Agent Data Collector (Scollector)

You can download Scollector to http://bosun.org/scollector/.

In Windows, for example, after downloading "Scollector-windows-amd64.exe", run "cmd.exe" as administrator. CD to file directory, enter "Scollector-windows-amd64-h docker-server-ip:8070" in the command window

The following information is displayed to establish a connection to the Bosun service. The command is as follows:

C:\>scollector-windows-amd64-h 192.168.1.101:80702016/11/18 15:59:19 Info:main.go:213:opentsdb host:http:// 192.168.1.101:8070

You can then see this server information in the Bosun items interface.

written in the last

At this point we have completed all the operations of the monitoring server. Like, please pay attention to, ~ feel good can order a recommendation, of course, also welcome the great god criticism.
