Alarm History Data Maintenance hst_alm.txt file

Hi

I am looking at how I can maintain and clear out old Alarm History, mainly as the Web App only likes to show the last 1000 records

I have looked at ftp and see that the permissions on the hst_alm.txt file  Owner,Group & Public Permissions attributes are set to   -r--r--r--.
Looks like we are only meant to read this file.

If I ftp, then modify this file,  and then by altering the attributes resend it back will it cause issues?

If its an issue, what is the preferred way of maintaining this file?  

Kind Regards
Dave

Dave,

Indeed, the hst_alm.txt is a read-only file. eWON will refuse to restore the file through FTP if you try it.
I checked in viewON and you are right. The alarm History object only shows the last 1000 alarms, mainly for performance reasons.
However, if you need to see the alarm history through web, you can use the following link : http://<eWONIP>/rcgi.bin/ParamForm?AST_Param=$dtAH$ftH

Hello,

I would like to show more than 1000 alarms in the alarm History object. Is it possible to change the size in a parameter or something like that ?
Attached is the alert message.


Thank you in advance for your help.
