Major overhaul of Docker support:

• New approach to improve stability across multiple versions of Docker
• Relies on Docker's syslog logging plugin
• Automatic collection of Docker metrics for all containers running on host
• Improved Dockerfiles to ease creating images with custom Scalyr Agent configuration
• Improved methods for configuring Scalyr Agent running within the container
• Customize where container log files are written
• See the Docker installation documentation for more details.

Additional features:

• New exclude option for writing log matching rules. When specifying which logs to collect using a glob pattern, you can exclude any of the matching logs using another glob. The field value should be an array of glob patterns.
• The import_vars feature has been extended to work in all files in the agent.d directory. The variables imported by a file are only applied to that file.
• Both the api_key and scalyr_server fields may now be set in any file in the agent.d directory.
• Initial support for compressing upload payloads

Bug fixes:

• Removed spurious exceptions in the linux_process_metrics module due to reading blank lines from /prod/pid/io
• Prevent log upload being wedged when encountering invalid utf-8 characters
• Prevent errors in Windows when file descriptors were attempted to be close
• More diagnostic output and defensive code for the linux_process_metrics module to help investigate issue

Wonderful Whale

Bug fixes:

• Fixed bug in linux_process_metrics causing errors when monitored process disappears

Querulous Quail

Features:

• Added ability to set HTTP and HTTPS proxies via configuration file. Use new configuration variables http_proxy and https_proxy. You must also set use_requests_lib to true.
• Report the number of open file descriptors held by a process for linux_process_metrics. The metric name is app.io.fds.
• The assigned the scalyrAgentLog parser to the agent log
• Added ability to skip the Scalyr connectivity check at agent start up using --no-check-remote-server.

Bug fixes:

• Added third-party library to fix issue with postgres_monitor.
• Added extra logging to track issue reported with Windows agent of silent shutdown.
• Fixed issue with haltBefore line grouper that prevented logs from being uploaded for several minutes.
• Changed default for line_completion_wait_time from 300 secs to 5 secs.
• Always delete the *.pyc files when doing an upgrade or uninstall

Quaint Quail

Features:

• Release of new snmp_monitor plugin, used to monitor SNMP devices

Bug fixes:

• Fix bug in windows_process_metrics when matching by commandline.
• Fix invalid character bug when parsing unicode characters with decimal value > 2^16
• Fix bug in shell_monitor plugin resulting in defunct processes lingering
• Fix bug in url_monitor plugin resulting in not emitting metric in some failure cases

Pugnacious Pig

Features:

• Integration of new request library, allowing routing through target specified by proxy environment variable. New library turned off by default for now. To turn on, set use_requests_lib.

Bug fixes:

• Fix windows_system_metrics monitor to no longer report disk usage on empty drives
• Fix mysql_monitor to recreate connection to db on failures
• Fix metrics names rather than throw errors when invalid metrics names are emitted by modules such as graphite.

Operating Otter

Features:

• Windows Event Log monitor now supports the EvtLog API implemented by Windows Vista and newer system. This allows for more expressive queries, as well as selecting events by severity level such as "Critical".

Bug fixes:

• Fix UTF-8 truncation bug in redis plugin.
• New option in redis plugin that controls logging of UTF-8 converstion errors. See the utf8_warning_interval for more details.
• Fix bug where network_interface_prefixes option was broken when listing multiple interfaces.
• Fix no attribute _tunnel_host bug with python 2.4 ssl library

Marauding Mouse

Features:

• Added plugin for reading SLOWLOG from redis
• Heavily optimized common path for copying logs to increase throughput

Neurotic Nightingale

Features:

• New sequence id and number implementation to help prevent events being added to the database multiple times
• Create new configuration option max_existing_log_offset_size to set a limit on how far back in a log file we are willing to go for a log file we have been previously copying.
• Enabled syslog_monitor for Windows platforms
• Preview release of windows_event_log_monitor, a monitor for copying the Windows event log to Scalyr.
• Preview release of docker support. E-mail [email protected] for more details
• Added new option network_interface_prefixes to linux_system_metrics monitor to override the prefix for monitored network interfaces.

Bug fixes:

• Fixed some race conditions in writing the pidfile on POSIX systems.
• Fixed bug causing agent to stop copying logs when previously copied logs are removed
• Disabled checking the command of the running agent process to guard against pid re-use since this was leading to some false negatives in the is the agent running checks.
• Remove exception logging when bad response received from server
• Print more informative message when server responds with server too busy
• Fix Utf-8 encoding bug with redaction rules

Moonstruck Monkey

Bug fixes:

• Added some extra diagnostic information to help investigate some customer issues

Loopy Lama

New features:

• Enable line groupers on the agent. Each log file may specify line grouping rules in its configuration. The agent can use this to group consecutive log lines together into a single logic log line. All future sampling and redaction rules will work on this single line instead of the individual log lines.

Bug fixes:

• Close file handles for files being scanned that have not had any activity in the last hour. Should fix too many open files bug.
• Reduce the default max_line_size value to 3400 to avoid truncation issues introduced by the server.
