See CHANGELOG.md for more details.

Utilities

• geneos - Manage Your Geneos environment

• dv2email - Send a Dataview as an EMail

• files2dv - Scan directories and files for information (not an FKM substitute!)

• gateway-reporter - Generate monitoring coverage reports from setup files

• libemail - Drop-In Updated Replacement for libemail

Integrations

• ServiceNow - Send Geneos Alerts to ServiceNow

• PagerDuty - Send Geneos to PagerDuty

Packages

These packages provide Go interfaces to ITRS Geneos as well as utilities to help build useful tools for working with ITRS Geneos.

• config

  Configuration support, based on the excellent viper package, with local extensions to add expansion of embedded references including AES encrypted values, interpolation of environment variables and other configuration parameters as well as reading local files and from URLs.

  A one-stop-shop to load and save configurations makes initialising programs easier and simpler.

  The implementation is slowly maturing but is not complete and is subject to API changes as we find better ways to do things. The options on those functions that have been extended allow fine grained control of how interpolation is performed including restricting which methods are supported and adding custom functions for interpolation/expansion.

• email

  Functions extracted from the libemail sources to be more generally available, initially for the dv2email program but also for additional tools in the future. libemail has not been changed so that it remains fully backward compatible.

• geneos

  Automate Geneos XML configuration file generation using Go programs.

  The Geneos schema is not, and cannot be, fully implemented at this stage as the mappings have been hand-rolled rather than any attempt as machine translation.

  • geneos/api

    An updated API package for sending data into Geneos. This is work in progress and is not ready for real-world use. This package will provide a unified API for both XML-RPC and REST APIs, within the constraints of the features of both.

• host

  Remote host integration extracted from geneos internal packages and turned into an extensible interface that supports local OS and remote SSH/SFTP operations. The API is still in flux and could do with more review and structure.

• plugins

• samplers

• streams

• xmlrpc

  These four packages provide support for the Geneos XML-RPC API Plugin.

• process

  Process management functions. There is a Daemon() function to background a process and the beginnings of program and batch managers. While the Daemon() function is relatively stable the other methods in this package are new and liable to change as their use matures.

• commands

  Geneos Gateway REST API Commands including programmatic support for snapshots of Dataviews. When used with the xpath package below it provides a simple way of executing REST commands on Geneos Gateways.

• xpath

  Geneos XPath handling functions and methods. This is a developing API and is not complete. Basic functionality exists to parse and manipulate simple XPaths.

• pkg/icp and pkg/gwhub

  These two packages are the start of APIs to ITRS Capacity Planner and Gateway Hub respectively. They are work in progress and should not be used for anything other than testing for the moment.

Index

• Variables
• func ExecutableName(version ...string) (execname string)
• func LogInit(prefix string, logfile ...string)
• func RenderHelpAsMD(command *cobra.Command)

Variables

var VERSION string

VERSION is a semi-global string variable

Functions

func ExecutableName

func ExecutableName(version ...string) (execname string)

ExecutableName returns a processed executable name. Symlinks are resolved and the basename of the resulting file has, at most, one extension removed and then if there is a '-' followed by the matching cordial version string. Note this final version string must match first version argument or the cordial one compiled into the binary.

For example:

`geneos.exe` -> `geneos`
`dv2email-v1.10.0` -> `dv2email`

func LogInit

func LogInit(prefix string, logfile ...string)

LogInit is called to set-up zerolog with our chosen defaults. The default is to log to STDERR.

If logfile is passed and the first element is not empty, then use that as the log file unless it is either "-" (which means use STDOUT (not STDERR) or equal to the os.DevNull value, in which case is io.Discard.

func RenderHelpAsMD

func RenderHelpAsMD(command *cobra.Command)

RenderHelpAsMD updated the given command to use glamour to render the command's Long description as markdown formatted text to an ANSI terminal.
