+# SVC Insights
+
+**SVCi** is a utility that collects metrics from one or more *IBM SAN Volume Controllers*. The metric data is processed and saved into an InfluxDB time-series database. Grafana is used to visualize the metrics data from InfluxDB through provided dashboards, or your own customized dashboards.
+
+This software is free to use and is licensed under the [Apache 2.0 License](https://bitbucket.org/mnellemann/svci/src/master/LICENSE), but is not supported or endorsed by International Business Machines (IBM).
+
+![architecture](doc/SVCi.png)
+
+
+## Installation and Setup
+
+There are few steps in the installation.
+
+1. Installation of InfluxDB and Grafana software
+2. Installation and configuration of *SVC Insights* (SVCi)
+3. Configure Grafana and import example dashboards
+
+### 1 - InfluxDB and Grafana Installation
+
+Install InfluxDB (v. **1.8.x** or **1.9.x** for best compatibility with Grafana) on a host which is network accessible by the SVCi utility (the default InfluxDB port is 8086). You can install Grafana on the same server or any server which are able to connect to the InfluxDB database. The Grafana installation needs to be accessible from your browser (default on port 3000). The default settings for both InfluxDB and Grafana will work fine as a start.
+
+- You can download [Grafana ppc64le](https://www.power-devops.com/grafana) and [InfluxDB ppc64le](https://www.power-devops.com/influxdb) packages for most Linux distributions and AIX on the [Power DevOps](https://www.power-devops.com/) site.
+- Binaries for amd64/x86 are available from the [Grafana website](https://grafana.com/grafana/download) (select the **OSS variant**) and [InfluxDB website](https://portal.influxdata.com/downloads/) and most likely directly from your Linux distributions repositories.
+- Create the empty *svci* database by running the **influx** CLI command and type:
+
+```text
+CREATE DATABASE "svci" WITH DURATION 365d REPLICATION 1;
+```
+
+See the [Influx documentation](https://docs.influxdata.com/influxdb/v1.8/query_language/manage-database/#create-database) for more information on duration and replication.
+
+### 2 - SVCi Installation & Configuration
+
+Install *SVCi* on a host, that can connect to your SAN Volume Controller (on port 7443), and is also allowed to connect to the InfluxDB service. This *can be* the same LPAR/VM as used for the InfluxDB installation.
+
+- Ensure you have **correct date/time** and NTPd running to keep it accurate!
+- The only requirement for **svci** is the Java runtime, version 8 (or later)
+- Install **SVCi** from [downloads](https://bitbucket.org/mnellemann/svci/downloads/) (rpm, deb or jar) or build from source
+  - On RPM based systems: ```sudo rpm -ivh svci-x.y.z-n.noarch.rpm```
+  - On DEB based systems: ```sudo dpkg -i svci_x.y.z-n_all.deb```
+- Copy the **/opt/svci/doc/svci.toml** configuration example into **/etc/svci.toml** and edit the configuration to suit your environment. The location of the configuration file can optionally be changed with the *--conf* option.
+- Run the **/opt/svci/bin/svci** program in a shell, as a @reboot cron task or configure as a proper service - there are instructions in the [doc/readme-service.md](doc/readme-service.md) file.
+- When started, *svci* expects the InfluxDB database to exist already.
+
+### 3 - Grafana Configuration
+
+- Configure Grafana to use InfluxDB as a new datasource
+  - **NOTE:** set *Min time interval* to *30s* or *1m* depending on your SVCi *update* setting.
+- Import example dashboards from [doc/dashboards/*.json](doc/dashboards/) into Grafana as a starting point and get creative making your own cool dashboards - please share anything useful :)
+
+## Notes
+
+### No data (or past/future data) shown in Grafana
+
+This is most likely due to timezone, date and/or NTP not being configured correctly on the SAN Volune Controller and/or host running SVCi.
+
+### Start InfluxDB and Grafana at boot (systemd compatible Linux)
+
+```shell
+systemctl enable influxdb
+systemctl start influxdb
+
+systemctl enable grafana-server
+systemctl start grafana-server
+```
+
+### InfluxDB Retention Policy
+
+Examples for changing the default InfluxDB retention policy for the svci database:
+
+```text
+ALTER RETENTION POLICY "autogen" ON "svci" DURATION 156w
+ALTER RETENTION POLICY "autogen" ON "svci" DURATION 90d
+```
+
+### Upgrading SVCi
+
+On RPM based systems (RedHat, Suse, CentOS), download the latest *svci-x.y.z-n.noarch.rpm* file and upgrade:
+```shell
+sudo rpm -Uvh svci-x.y.z-n.noarch.rpm
+```
+
+On DEB based systems (Debian, Ubuntu and derivatives), download the latest *svci_x.y.z-n_all.deb* file and upgrade:
+```shell
+sudo dpkg -i svci_x.y.z-n_all.deb
+```
+
+Restart the SVCi service on *systemd* based Linux systems:
+
+```shell
+systemctl restart svci
+journalctl -f -u svci  # to check log output
+```
+
+
+### AIX Notes
+
+To install (or upgrade) on AIX, you need to pass the *--ignoreos* flag to the *rpm* command:
+
+```shell
+rpm -Uvh --ignoreos svci-x.y.z-n.noarch.rpm
+```
+
+
+## Known problems
+
+
+## Development Information
+
+You need Java (JDK) version 8 or later to build svci.
+
+
+### Build & Test
+
+Use the gradle build tool, which will download all required dependencies:
+
+```shell
+./gradlew clean build
+```
+
+### Local Testing
+
+#### InfluxDB
+
+Start the InfluxDB container:
+
+```shell
+docker run --name=influxdb --rm -d -p 8086:8086 influxdb:1.8
+```
+
+Create the *svci* database:
+
+```shell
+docker exec -i influxdb influx -execute "CREATE DATABASE svci"
+```
+
+
+#### Grafana
+
+Start the Grafana container, linking it to the InfluxDB container:
+
+```shell
+docker run --name grafana --link influxdb:influxdb --rm -d -p 3000:3000 grafana/grafana
+```
+
+Setup Grafana to connect to the InfluxDB container by defining a new datasource on URL *http://influxdb:8086* named *svci*.
+
+
+Grafana dashboards can be imported from the *doc/dashboards/* folder.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
