Ithkul

Features:

• Added journald_monitor for collecting logs from a local journald service. Requires installation of the Python systemd library.
• Added garbage_monitor for debugging memory consumption issues in the agent.
• Added verify_k8s_api_queries option to the kubernetes_monitor to allow disabling SSL verification on local API calls.

Bug fixes:

• Fixed issues causing the linux_process_metrics_monitor to throw exceptions when the monitored process dies.
• Additional debug flags to aide in investigating memory issues with the agent.

Horta

Features:

• Relaxed configuration rules to allow for any config option to be specified in a configuration fragment in the agent.d directory.

Bug fixes:

• Fixed bug in linux_process_metrics that would generate errors when a monitored process died
• Fixed issue in the docker and kubernetes monitors that would prevent the agent from sending logs from short lived containers
• Fixed issue in the docker and kubernetes monitors that could cause the tail end of a containers logs to not be uploaded after it exits
• Fixed issue in docker monitor where the metrics_only config option was not being obeyed.
• Added various options to help investigate memory leak

Fallers

• Added kubernetes support with introduction of new kubernetes monitor along with kubernete image published on dockerhub.com under scalyr/scalyr-k8s-agent. See online documentation for more information.
• Added network_interface_suffix option to linux_system_metrics monitor to control regular expression used to validate interfaces names. Additionally, widened existing rule to accept letters at the end of the interface name.
• Added aggregate_multiple_processes to linux_process_metrics which allows multiple processes to be matched by process matching rule. The reported metrics will include the statistics from all matching processed.
• Added include_child_processes to linux_process_metrics to include all child processes from the matched process in the reported metrics.

Ewoks

Features:

• Changed default for max_line_size to 9900 to match new larger message field support on the server.

Bug fixes:

• Fixed bug causing the Docker plugin to leak file descriptors as new containers were added while using the docker_api mode.

Dyson Aliens

Features:

• Support to parse log lines written as a JSON object to extract line content before sending to Scalyr. You may turn this on by setting parse_lines_as_json to true in your log configuration stanza for a particular file. This is useful when uploading raw Docker logs.
• Read the Scalyr api key from an environment variable
• Add support for PUT requests to the http_monitor.
• Add support for replacing redacted values with a hash of the actual value. See the redaction documentation for more details.

Bug fixes:

• Fix win32 build such that it correctly pulls packages from the third party repository. This fixes a bug resulting in SOCK5 proxy support not working under Windows.

Changling

New features:

• Upgraded requests library to support new proxy protocols such as SOCKS5. To use SOCKS5, use either the socks5 or socks5h protocol when specifying the proxy address (socks5 resolves DNS addresses locally, whereas socks5h resolves addresses at the SOCKS5 server).

For example, to use a SOCKS5 proxy to proxy traffic to Scalyr, you would add the following to your agent.json configuration file:

use_requests_lib: true,                                              // Proxy support requires use of the request library.
https_proxy: "socks5://yoursocksserver.company.com:8080”             // Replace with your SOCKS5 address

Bug fixes:

• Fix bug preventing multiple instances of the syslog_monitor from logging to separate log files.

Borg

2.0.27 "Borg" - Jun 2, 2017

New features:

• Added new option report_container_metrics to docker_monitor to allow disabling of gathering and reporting metrics for each Docker container.

Bug fixes:

• Fix recent breakage causing the run_monitor code to fail.
• Fix error / warning logging in syslog_monitor to better capture issues with Docker support.

Anomine

New features:

• Added feature to allow completely disabling the use of the Docker socket in certain Docker configurations.
• New max_log_size and max_log_rotations configuration options that can be used to set the maximum length an agent-generated log file can grow before it is rotated and the maximum number of rotations to keep.

Bug fixes:

• Fix bug preventing rotated Docker files from being deleted
• Fix bug that resulted in https_proxy and ``http_proxy` configuration options being ignored.

Zany Zebra

New features:

• Docker integration: Old docker log files will be deleted after unused for 1 day (by default).
• Change to pidfile format in preparation for better systemd support

Bug fixes:

• Syslog/Docker fix that was causing logs being uploaded with default parser instead of user-specified parser
• Minor fixes for BMP unicode

Yucky Yak

New features:

• New rename_logfile option to change the file name and path for a log file when uploading it to Scalyr.
• New copy_from_start option to instruct the agent to copy a log file from its start when it first matches.
• New metric in linux_system_metrics to record number of CPUs used by a machine. Metric name is sys.cpu.count.
• New strip_domain_from_default_server_host configuration option to remove any domain name from serverHost when using the default value.

Bug fixes:

• Syslog/Docker fix that generated a port already in use error when reading new configuration file
• Syslog/Docker fix that caused dropped log lines when write rate exceeded certain threshold
• Syslog CPU performance improvements
