What is the name of Windows service of EasyNetMonitor SE?
The service name is EasyNetMonitorSrv.
Which should be settings of host if we would like to send an email after
3 consecutive "lost connection messages", and then send an email, when the host is available again,
but only after its status is "stable" (after 6 "online" messages)?
You can use the the emulator mode in ENM for testing.
Emails will be not send and will appear in "Emulator" window only.
Create the simple txt file in ENM folder: enm_emu_offline_list.txt.
If your host will be in start of some line of the text in this file - so ENM get "lost connection" message after ping for this host.
For testing is useful to disable ENM monitor on some time and send pings from "Ping now" window for this host only.
The settings in "Options->Email options" window are active for all hosts.
If this options are active so will be send log file with info from all hosts.
You can not use this options in your case.
What is the test (emulator) mode?
This is a test mode for configuring notifications, e-mail messages and actions.
Mode is activated if the text file enm_emu_offline_list.txt exists in the program folder.
In this mode, the service (or EasyNetMonitor PRO) stops sending the real ping command to all hosts
and gets information about "lost connection" hosts from this file.
Addresses of this hosts are listed at the beginning of the lines in this file.
All other hosts are "online".
In this mode, the actual e-mails will be not sent and actions will be not started.
However, the information that the email should send and the action should run appears in the emulator message box.
This emulator message box opens automatically.
The addresses in the file should be at the beginning of the line.
For example: google.com
cnn.com
vk.com
This means that hosts google.com, cnn.com, vk.com are "lost connection".
If the address is not in the beginning of the line, that it is "online".
For example: google.com
..cnn.com
//vk.com
Hosts cnn.com and vk.com are "online". But there is no connection to google.com.
You can open the file enm_emu_offline_list.txt in the text editor (Notepad),
make changes and click "Save file" without closing the editor.
If the program is installed in the Program Files, then run editor (Notepad) with administrator rights please.
Please rename or delete this file to stop test (emulator) mode.
It is not necessary to restart the service EasyNetMonitorSrv in EasyNetMonitor SE.
EasyNetMonitor SE is the Windows service version of EasyNetMonitor PRO.
