MonitorUI - Infrastructure, network and services monitoring

MonitorUI is agent less infrastructure, network and services monitoring

First, there is no UI (User interface), it was thought about it at beginning, but there are more important things, like life itself :) But do not worry, MonitorUI does great job, it has really good notifications via mail and very nice logs. Who wants another dashboard when you can integrate through logs with such great tool like Grafana, Kibana, Splunk (this is not the advertisement) etc. Also it does pretty nice color outputs on terminal, so your eyes will not be lost in shadows.

Console output

Ok, what MonitorUI can do for me ?

Generally

• Agents / probes free monitoring - No installation required on monitored hosts / clients, MonitorUI use wide general TCP/UDP protocols and Services (HTTP / HTTPS, WMI, DB connectors) to monitor the hosts.

• Supported OSses: Windows, Linux, Freebsd, Unix etc. Also you can run it from the cloud or anywhere where Python 3 works, like https://www.pythonanywhere.com (again, this is not an advertisement, just hints).

• Advance notification - email recipients configurable per monitored site (monitored host)

• Log format is prepared for machine processing

Network monitoring

• Ping
• Port (unlimited ports per host)
• SSL Certificate expiration check (configurable notification period before certificates expiration)

Web functions monitoring

• URL Response Code (useful to check if site is reachable or monitor health-checks)
• Web changes (check if web pages has changed between check, useful to monitor if website, health check is same or changed. You can define to ignore HTML elements if they are generated dynamically)

Oracle DB

• SQL Query to compare against expected result, need to uncoment cx-Oracle in /install/requirements_win.txt, requirements_linux_freebsd.txt

SQLite DB

• SQL Query to compare against expected result

WMI - MS Windows

• Windows processes, check if Windows process(es) runs or not. (This functionality is available only if MonitorUI is installed on Windows)

Other type of check needed? Write us feedback, we are open to all of ideas ;).

Performance and where I can use it ?

Performance

Currently the biggest deployment about which we know is monitoring of 150+ servers and on each it performs 3 - 4 checks, which means 600 checks each few minutes. The MonitorUI can performs this in cca. 15 seconds (quite good).

Where I Can use it ?

There are no limitations from us, it fits everywhere where you need monitor internal or external services and infrastructure. MonitorUI does not use any probes, so it literary works Out of Box.

I want it, how can I install ? (Full installation steps, including Python)

Windows

1. Download and install Python version 3.8x - 3.10.x from https://www.python.org which fits to your Windows version. During the installation do not forget to "check" on first screen "Add python.exe to PATH". If you missed it, do not worry, just uninstall and install Python 3 again and check the "add path". By end of installation process select Disable path length limit.

   • Why Python 3.8.x - 3.10.x? it is because compatibility of Oracle (cx_oracle). If you want newest python, there is no issue, just remove "cx_oracle" from "\install\requirements_win.txt"
   • If you do not want to use OracleDB monitoring script, use any new python

2. Restart machine (PC, Server etc ..), to activate the PATH Variable

3. Download MonitorUI from Github https://github.com/lmoravek83/monitorui/

4. Unzip from "monitorui-[version].zip" content in to folder where you want to have MonitorUI placed

5. In the folder "monitorui-master\install" is "install_windows.bat". Running this script It will be installed necessary python packages from pypi.org (store for python libraries)

    install_windows.bat
   

6. That is all :) Now proceed to Configuration part

   • Also you can use git clone, make Python venv, but this is out of scope of this manual (we want keep it simple)

Linux / FreeBSD

1. Install Python 3.8.x - 3.10.x (source code, packages, whatever suits to you) and python pip package manager. If you already have these requirements, you can skip this point

   • Example for Debian (type) distribution:

       sudo apt install python3
     
       sudo apt install python3-pip
     

   • Example for FreeBSD (privileged account to install right is required)

       pkg pkg install python39
     
       pkg pkg install py39-pip
     

   • Example for FreeBSD (sudo users)

       sudo pkg install python39
     
       sudo pkg apt install py39-pip
     

   • Why Python 3.8.x - 3.10.x? it is because compatibility of Oracle (cx_oracle). If you want newest python, there is no issue, just remove "cx_oracle" from "\install\requirements_win.txt".

   • With similar way is possible to install on all unix(like) systems

2. Download MonitorUI from Github https://github.com/lmoravek83/monitorui/releases

3. Unzip from "monitorui-[version].zip" content in to folder where you want to have MonitorUI placed

4. In the folder "monitorui-master/install" is "install__linux_freebsd.sh". Running this script It will be installed necessary python packages from pypi.org (store for python libraries)

   Run from from ./install directory:

    sh install_linux_freebsd.sh
   

5. That is all :) Now proceed to Configuration part

   • Also you can use git clone, make Python venv, but this is out of scope of this manual (we want keep it simple)

Configuration

After the installation there are two directories in MonitorUI folder: "config" and "Sites". Both folder contains example values of general MonitorUI and sites (monitored hosts) configuration.

General Configuration

"config.json" under "config" folder contains general configuration for MonitorUI. All values are optional. Is recommended to fullfil SMTP / email configuration parameters as minimum. Create new one or adjust one which is already there.

{
  "sitesfolder": ".//sites", // Folder where are stored sites to be monitored (Optional, default value: .//sites)
  "smtpserver": "smtp.gmail.com", // SMTP server for email notification (Optional, default value: '')
  "smtpport": 587, // SMTP port of email server (Optional, default value: 25)
  "smtpssl": true, // SSL over SMTP (Optional, default value: False)
  "smtpauthentication": true, // Switch to enable SMTP authentication (Optional, default value: False)
  "smtpuser": "", // SMTP User (Optional, default value: "")
  "smtppassfilelocation": ".//config//5fbTeZ9GUsYeaHxF", //SMTP Password taken from file (optional)
  "smtppass": "", // If password file does not exist, use this value (Optional, default value: '')
  "from_email": "[email protected]", // Email from which notification being send (Optional, default value: '')
  "workinloop": false, // In case that you want to run monitoring as service (Optional, default value: False)
  "loopintervallmin": 5, // If workinloop = True, set minimal time in sec. to re-run monitoring (Optional, default value: 300)
  "loopintervallmax": 10, // If workinloop = True, set maximal time in sec. to re-run monitoring (Optional, default value: 300)
  "logsretention": 60, // Logs Retention period, if not used or None, no logs retention (Optional, default value: None)
  "log_daily_feed": true, // Copy last daily log of each site under ./logs/log_daily_feed/ for logs processing (Optional, default value: False)
  "parallel_checks": true, // Monitoring can run the checks of sites (monitored hosts) in parallel (Optional: default value: False) 
  "max_workers": 5, // Maximum parallel threads (Optional, default value: 5)  "timeout_email": 10 // Set time out for email services (Optional, default value: None)
}

Use the example config from folder ./config/config.json, as this commented documentation is not valid JSON.

Site Configuration

How to add new site (host) to be monitored

* Note, bellow directory structure use the UNIX convection, For Windows users, just change in your mind during reading "/" with "\" :)

1. Under folder "./sites/" create system name folder (Example: MY_Application_PROD etc.) If you extracted package properly, there is already sample folder "git_servers"

2. Under "./sites/MY_Application_PROD/" create new site folder (Example: Server01.mydomain.com)

   • The final path for example will be "./sites/MY_Application_PROD/Server01.mydomain.com"

3. Create new or copy "configsite.json" from example ./sites/git_servers/github/ in to your site folder

4. With this approach you can create unlimited sites grouped in to the related folders (based on system, environments etc.)

How to configure site

For each site is required to create "configsite.json", you can use example which is delivered along with the package.

{
  "sitename": "Github", // Name of the site (monitored host), if not configured, is used direcotry name
  "hostname": "www.github.com", // Hostname for ping, port checks
  "siteurl": "https://github.com/pallets/click", // URL Site for SSL Certificate check, WEB check, HTTPs response check
  "siteenviroment": "PROD", // Type of environment (Production, tests, etc)
  "systemname": "github", // Name of the system, or different grouping and logs identification (Optional), if not configured, is used directory of system
  "monitoringstart": "000000", // From which time is monitoring of site enabled (Optional)
  "monitoringend": "235959", // Until which time is monitoring of site enabled (Optional)
  "tags": [""],
  "monitoringdays": [0, 1, 2, 3, 4, 5, 6], // On which days is monitoring enabled on the host, 0 = sunday (Optional)

  "checkhostport": true, // Switch to enable or disable Port check (Optional, default value: False)
  "hostports": [ "443", "80" ], // Ports to be checked. Example:  [ "80" ]  or [ "443", "80" ] (Mandatory if checkhostport = true , default value: "")
  "checkcertificateexpiration": true, // Switch to enable or disable Certificate Expiration check (Optional, default value: False)
  "certificateexpirationtrigger1": 30, // How many days before certificate expiration notification is triggered (Optional, default value: 30)

}

Oracle DB drivers

For Oracle DB check needs to be installed oracle Driver.

Oracle Instant Client

1. Download "Basic Light Package" which suits to your system

2. Unpack in folder where you want to have the Oracle DB drivers

3. Adjust path in "./modules/functions/oracledb.py" Line: "cx_Oracle.init_oracle_client(lib_dir=r"C:\oracle\instantclient_21_3")"

How to run MonitorUI

Windows

run in Windows Command line / Power shell "monitor_ui.bat" or you can add it in scheduled tasks:

monitorui_run.bat

or

python monitorui.py

Linux

run in Shell or you can add it in to the crontab (do not forget for full path):

sh monitorui_run.sh

or

python ./monitorui.py

or

python3 ./monitorui.py

Logs

Info: Logs keeps same structure, so they can be easily processed (OK, Warning, Error) in to logs machine processing platform (Grafana, Kibana, Splunk etc...)

General Logs

/logs/monitor_DDMMYYYYY.log - store daily logs which contains information from each run, failures and other issues. Also contains when each run starts and ends, including duration

Logs for machine data processing (Splunk, Grafana, Kibana etc ..)

/logs/log_daily_feed/sitename.log - store daily log of each moniterd site / host. in this folder are stored last logs from all minitored sites / hosts.

Site logs

/sites/system/site/logs/sitename_DDMMYYYYY.log contains details of each check and result
