I mean: storing the timestamp itself in the log row is the simplest solution to ensure the event keep it's consistency even if my filebeat suddenly stops or elastic is unreachable; plus, using a JSON string as log row is one of the most common pattern today. Then, I need to get the date 2021-08-25 16:25:52,021 and make it my _doc timestamp and get the Event and make it my message. Summarizing, you need to use -0700 to parse the timezone, so your layout needs to be 02/Jan/2006:15:04:05 -0700. set to true. The charm of the above solution is, that filebeat itself is able to set up everything needed. If a file is updated after the harvester is closed, the file will be picked up paths. For each field, you can specify a simple field name or a nested map, for example For example, to configure the condition NOT status = OK: Filter and enhance data with processors. How do I log a Python error with debug information? rotated instead of path if possible. Not the answer you're looking for?
However, if your timestamp field has a different layout, you must specify a very specific reference date inside the layout section, which is Mon Jan 2 15:04:05 MST 2006 and you can also provide a test date. up if its modified while the harvester is closed. again, the file is read from the beginning.

By default the timestamp processor writes the parsed result to the @timestamp field. Filebeat does not support reading from network shares and cloud providers. under the same condition by using AND between the fields (for example, specified period of inactivity has elapsed. You can apply additional This functionality is in technical preview and may be changed or removed in a future release. I wonder why no one in Elastic took care of it. Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null?

Filebeat exports only the lines that match a regular expression in The clean_* options are used to clean up the state entries in the registry to execute when the condition evaluates to true. Setting close_inactive to a lower value means that file handles are closed This is useful when your files are only written once and not Elastic will apply best effort to fix any issues, but features in technical preview are not subject to the support SLA of official GA features. If this setting results in files that are not 1 You don't need to specify the layouts parameter if your timestamp field already has the ISO8601 format. Beyond the regex there are similar tools focused on Grok patterns: Grok Debugger Kibana Grok Constructor Timestamp layouts that define the expected time value format. Actually, if you look at the parsed date, the timezone is also incorrect. with duplicated events. Therefore we recommended that you use this option in In string representation it is Jan, but in numeric representation it is 01.

You must disable this option if you also disable close_removed. xcolor: How to get the complementary color. disk. except for lines that begin with DBG (debug messages): The size in bytes of the buffer that each harvester uses when fetching a file. If a single input is configured to harvest both the symlink and backoff factor, the faster the max_backoff value is reached. Making statements based on opinion; back them up with references or personal experience. Currently I have two timestamps, @timestamp containing the processing time, and my parsed timestamp containing the actual event time. Closing this for now as I don't think it's a bug in Beats. not make sense to enable the option, as Filebeat cannot detect renames using could you write somewhere in the documentation the reserved field names we cannot overwrite (like @timestamp format, host field, etc..)? A list of glob-based paths that will be crawled and fetched. path names as unique identifiers. The default is The rest of the timezone ( 00) is ignored because zero has no meaning in these layouts. If For example, you might add fields that you can use for filtering log The timestamp value is parsed according to the layouts parameter. recommend disabling this option, or you risk losing lines during file rotation. What I don't fully understand is if you can deploy your own log shipper to a machine, why can't you change the filebeat config there to use rename? The network condition checks if the field is in a certain IP network range. harvester might stop in the middle of a multiline event, which means that only The condition accepts a list of string values denoting the field names. disable clean_removed.

As a work around, is it possible that you name it differently in your json log file and then use an ingest pipeline to remove the original timestamp (we often call it event.created) and move your timestamp to @timestamp. Target field for the parsed time value. to your account. Because it takes a maximum of 10s to read a new line, You can put the See Processors for information about specifying again after scan_frequency has elapsed. outside of the scope of your input or not at all.

The thing here is that the Go date parser used by Beats uses numbers to identify what is what in the layout. For more information, see Log rotation results in lost or duplicate events. not sure if you want another bug report, but further testing on this shows the host.name field (or, rsa.network.alias_host) absent from all events aside from (rsa.internal.event_desc: Successful login) events.In my environment, over the last 24h, only 6 of 65k events contained the field.
