If no time period or bucket is specified it defaults to the time range of the Search.Įxample 1: Checking the server distribution over time to make sure the load balancer is working properly.However, you’ll want to avoid these situations whenever they cause perceptible slowness in games. If you use timeslice with the compare or outlier operators, do not alias timeslice. CPUs are designed to run safely at 100 CPU utilization.For example, if your query specifies 150 buckets, Sumo Logic will find a reasonable clock-aligned resolution to return approximately 150 buckets in the query results. The number of buckets in your query is a target or maximum, not necessarily the exact number of buckets that will be returned.The timeslice operator must be used with an aggregating operator such as count by or group by.After you’ve timesliced the data into buckets, the transpose operator allows you to plot aggregated data in a time series. The timeslice operator is commonly used in conjunction with the transpose operator.Creates a field named _timeslice_end that marks the end of the timeslice in milliseconds.If an alias is not provided, a default _timeslice field is created that marks the start of the timeslice in milliseconds. An alias for the timeslice field is optional.Messagetime_ms - receipttime_ms as diff_ms |įormatDate(_timeslice, 'yyyy-MM-dd') as day |Ĭount as count, min(receipttime_ms) as oldest_receiptime_ms, max(receipttime_ms) as latest_receiptime_ms, min(absolute_time_diff_ms) as min_time_diff_ms, max(absolute_time_diff_ms) as max_time_diff_ms group by day, _sourceName |įormatDate(fromMillis(toLong(oldest_receiptime_ms)), 'yyyy-MM-dd HH:mm:ss.SSS') as oldest |įormatDate(fromMillis(toLong(latest_receiptime_ms)), 'yyyy-MM-dd HH:mm:ss. be sure to click 'Use Receipt Time' when running this query The following query will show you if you have messages where the receipt time and message time are off by more than a minute. Also, I haven't tested anything beyond the default settings, I believe you have flexibility here with respect to how message times are set and what date format is used on ingest, according to this.

Note that you're free to modify the pattern layout after the date string. If this is left out or is incorrect, then this can result in messages being assigned incorrect message times at ingest which means you won't see them in queries in the expected timeframe(unless you specify 'Use Receipt Time'). Per Sumo support, for the logback appender the correct date format is. Make sure your pattern layout begins with the proper date format, otherwise the default behavior of the ingest is to search for dates in your message string.

The relevant section in log4j2.xml would look like this '> If your message queue is bigger, it is recommended to increase this setting or else risk loss of data in ingestion MaxQueueSizeBytes is another optional setting set to 1000000 by default for maximum capacity (in bytes) of the message queue. Appender logs may or may not (depending on the version of the Appender) display the following example log message 11:12:21,005 Log4j2-TF-1-AsyncLoggerConfig-1 WARN Evicted 1 messages from buffer Resolution:Įnsure the following settings are configured correctlyįlushAllBeforeStopping - is an optional setting that should be set to true since it will flush all messages before stopping regardless of flushingAccuracyMs and avoid potential loss of data in ingestion. We have been losing log messages at the Sumologic collection receivers using hosted HTTP collectors that are serving as the endpoint for log messages (via log4j2.xml config file)Ībsence of configuration of flushAllBeforeStopping can cause current data in the buffer not to be ingested into Sumo Logic if the appender terminates abnormally.Ībsence of configuration for maxQueueSizeBytes would utilize the default 1million bytes for the buffer size and if the size of the data set to be ingested exceeds that, then we have seen data not be ingested into Sumo Logic.
