Logging Data

devices. This information is suitable for graphing and viewing in textual format. Status and error logs
contain information collect about the status of Sensorsoft Alert and errors encountered. This information is
only suitable for viewing in textual format and cannot be graphed. Both of these log files are recorded in
text delimited format with date and time stamps.
Status and Error Logs
Sensorsoft Alert records the following status and error logs:
1. alertd.log:
2. webaccess.log
Contains systems messages and errors.
Contains web server events for user login, logout, and failed login. This log file
can be viewed from the admin account only.

4. smtp.log: Contains email alerts that have been sent.
5. pager.log: Contains pager alerts that have been sent.
6. commandline.log: Contains command line alerts that have been executed.
By default, the above log files are recorded locally on the Alert appliance, and will contain only the most
recent 200 entries. You can also configure Alert to record log files on a remote server using NFS (Network
File System). By recording log files on an NFS server, there will be no limit on the number of entries
stored in the log files. To learn more about NFS logging, please see the section Logging Data on a NFS
Server.
Data file Naming Convention
Sensorsoft Alert names data files to be unique. All data log files are named in the format

port the monitored device is connected to and the variable index on the device. This can be determined
from the device configuration page of the device in question.
