![]() ![]() At the beginning of message: A line that matches the specified pattern marks the beginning of a new message non-matching lines are grouped into the prior message.In Source File Path, type the path information.In Flat File Policy Name, type a descriptive name.Access the Log Management Policies page and click the Flat File tab.Also, the collection policy can specify when Alert Logic collects messages from associated log sources. ![]() The collection policy determines which Flat File log messages to collect, how to separate log messages within a Flat File, and how to read the time of each log message. Choose one of several predefined rules.Choose the local time zone and settings of the log source.This pattern can be a simple Perl Compatible Regular Expression (PCRE).Ĭhoose one of the following options to configure the time stamp for each Flat File: Use a known pattern that matches the beginning, middle, or end of each log message.Define a fixed number of lines per log message, or.When a single message spans multiple lines, you must: Choose a single or multi-line logīy default, Alert Logic assumes that each message is contained on a single line. For example, Flat Files may contain variable data like dates in MM.DD.YYYY (month, day, year) or DD.MM.YYYY (day, month, year) format.įor Linux users, the Alert Logic console automatically detects standard Linux log rotation formats and also provides other common formats for selection during setup. The rotation scheme is the order that the date appears within the log message. Other similar formats are also supported, and is based on the date in each file name according to the pattern provided:.Alert Logic collects from each file in order, based on the numeric suffix.Periodically, the active log file is renamed to.Incrementing Integer Method (logrotate).Alert Logic collects from each file in order, based on the timestamp in each file name.The currently active log file is given the form.Periodically, a new log file is created and becomes the active log file.Alert Logic collects from each file in order, based on the date in each file name.Periodically, a new active file is created and the old active file is renamed to reflect the date: YYYYMMDD.log.The following is a list of supported Flat File rotation format examples: The order in which rotated log files are collected (such as which files have the oldest or most recent messages).Rotated log files into which no new log messages are written.The active log file into which new log messages are written.When you define a log rotation schema, you instruct Alert Logic how to identify: Alert Logic supports gzip, bzip2, and zip compressed logs. As a result, log formats vary by computer device. No industry standard exists to structure Flat File log messages. Configurations for Flat File collection policy If you update, archive, or delete any collection or policies, you could break interconnected configurations. ![]()
