# Running Telegraf as a Windows Service
If you have tried to install Go binaries as Windows Services with the **sc.exe**
tool you may have seen that the service errors and stops running after a while.
**NSSM** (the Non-Sucking Service Manager) is a tool that helps you in a
[number of scenarios](http://nssm.cc/scenarios) including running Go binaries
that were not specifically designed to run only in Windows platforms.
## NSSM Installation via Chocolatey
You can install [Chocolatey](https://chocolatey.org/) and [NSSM](http://nssm.cc/)
with these commands
```powershell
iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
choco install -y nssm
```
## Installing Telegraf as a Windows Service with NSSM
You can download the latest Telegraf Windows binaries (still Experimental at
the moment) from [the Telegraf Github repo](https://github.com/influxdata/telegraf).
Then you can create a C:\telegraf folder, unzip the binary there and modify the
**telegraf.conf** sample to allocate the metrics you want to send to **InfluxDB**.
Once you have NSSM installed in your system, the process is quite straightforward.
You only need to type this command in your Windows shell
```powershell
nssm install Telegraf c:\telegraf\telegraf.exe -config c:\telegraf\telegraf.config
```
And now your service will be installed in Windows and you will be able to start and
stop it gracefully

# Amazon CloudWatch Statistics Input
This plugin will pull Metric Statistics from Amazon CloudWatch.
### Amazon Authentication
This plugin uses a credential chain for Authentication with the CloudWatch
API endpoint. In the following order the plugin will attempt to authenticate.
1. [IAMS Role](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html)
2. [Environment Variables](https://github.com/aws/aws-sdk-go/wiki/configuring-sdk#environment-variables)
3. [Shared Credentials](https://github.com/aws/aws-sdk-go/wiki/configuring-sdk#shared-credentials-file)
### Configuration:
```toml
[[inputs.cloudwatch]]
## Amazon Region (required)
region = 'us-east-1'
## Requested CloudWatch aggregation Period (required - must be a multiple of 60s)
period = '1m'
## Collection Delay (required - must account for metrics availability via CloudWatch API)
delay = '1m'
## Override global run interval (optional - defaults to global interval)
## Recomended: use metric 'interval' that is a multiple of 'period' to avoid
## gaps or overlap in pulled data
interval = '1m'
## Metric Statistic Namespace (required)
namespace = 'AWS/ELB'
## Metrics to Pull (optional)
## Defaults to all Metrics in Namespace if nothing is provided
## Refreshes Namespace available metrics every 1h
[[inputs.cloudwatch.metrics]]
names = ['Latency', 'RequestCount']
## Dimension filters for Metric (optional)
[[inputs.cloudwatch.metrics.dimensions]]
name = 'LoadBalancerName'
value = 'p-example'
```
#### Requirements and Terminology
Plugin Configuration utilizes [CloudWatch concepts](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html) and access pattern to allow monitoring of any CloudWatch Metric.
- `region` must be a valid AWS [Region](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#CloudWatchRegions) value
- `period` must be a valid CloudWatch [Period](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#CloudWatchPeriods) value
- `namespace` must be a valid CloudWatch [Namespace](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Namespace) value
- `names` must be valid CloudWatch [Metric](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Metric) names
- `dimensions` must be valid CloudWatch [Dimension](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Dimension) name/value pairs
#### Restrictions and Limitations
- CloudWatch metrics are not available instantly via the CloudWatch API. You should adjust your collection `delay` to account for this lag in metrics availability based on your [monitoring subscription level](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-cloudwatch-new.html)
- CloudWatch API usage incurs cost - see [GetMetricStatistics Pricing](https://aws.amazon.com/cloudwatch/pricing/)
### Measurements & Fields:
Each CloudWatch Namespace monitored records a measurement with fields for each available Metric Statistic
Namespace and Metrics are represented in [snake case](https://en.wikipedia.org/wiki/Snake_case)
- cloudwatch_{namespace}
- {metric}_sum (metric Sum value)
- {metric}_average (metric Average value)
- {metric}_minimum (metric Minimum value)
- {metric}_maximum (metric Maximum value)
- {metric}_sample_count (metric SampleCount value)
### Tags:
Each measurement is tagged with the following identifiers to uniquely identify the associated metric
Tag Dimension names are represented in [snake case](https://en.wikipedia.org/wiki/Snake_case)
- All measurements have the following tags:
- region (CloudWatch Region)
- unit (CloudWatch Metric Unit)
- {dimension-name} (Cloudwatch Dimension value - one for each metric dimension)
### Example Output:
```
$ ./telegraf -config telegraf.conf -input-filter cloudwatch -test
> cloudwatch_aws_elb,load_balancer_name=p-example,region=us-east-1,unit=seconds latency_average=0.004810798017284538,latency_maximum=0.1100282669067383,latency_minimum=0.0006084442138671875,latency_sample_count=4029,latency_sum=19.382705211639404 1459542420000000000

# Example Input Plugin
This input plugin will test HTTP/HTTPS connections.
### Configuration:
```
# List of UDP/TCP connections you want to check
[[inputs.http_response]]
## Server address (default http://localhost)
address = "http://github.com"
## Set response_timeout (default 5 seconds)
response_timeout = 5
## HTTP Request Method
method = "GET"
## HTTP Request Headers
[inputs.http_response.headers]
Host = github.com
## Whether to follow redirects from the server (defaults to false)
follow_redirects = true
## Optional HTTP Request Body
body = '''
{'fake':'data'}
'''
```
### Measurements & Fields:
- http_response
- response_time (float, seconds)
- http_response_code (int) #The code received
### Tags:
- All measurements have the following tags:
- server
- method
### Example Output:
```
$ ./telegraf -config telegraf.conf -input-filter http_response -test
http_response,method=GET,server=http://www.github.com http_response_code=200i,response_time=6.223266528 1459419354977857955

# sysstat Input Plugin
Collect [sysstat](https://github.com/sysstat/sysstat) metrics - requires the sysstat
package installed.
This plugin collects system metrics with the sysstat collector utility `sadc` and parses
the created binary data file with the `sadf` utility.
### Configuration:
```toml
# Sysstat metrics collector
[[inputs.sysstat]]
## Path to the sadc command.
#
## On Debian and Arch Linux the default path is /usr/lib/sa/sadc whereas
## on RHEL and CentOS the default path is /usr/lib64/sa/sadc
sadc_path = "/usr/lib/sa/sadc" # required
#
#
## Path to the sadf command, if it is not in PATH
# sadf_path = "/usr/bin/sadf"
#
#
## Activities is a list of activities, that are passed as argument to the
## sadc collector utility (e.g: DISK, SNMP etc...)
## The more activities that are added, the more data is collected.
# activities = ["DISK"]
#
#
## Group metrics to measurements.
##
## If group is false each metric will be prefixed with a description
## and represents itself a measurement.
##
## If Group is true, corresponding metrics are grouped to a single measurement.
# group = true
#
#
## Options for the sadf command. The values on the left represent the sadf options and
## the values on the right their description (wich are used for grouping and prefixing metrics).
##
## Run 'sar -h' or 'man sar' to find out the supported options for your sysstat version.
[inputs.sysstat.options]
-C = "cpu"
-B = "paging"
-b = "io"
-d = "disk" # requires DISK activity
"-n ALL" = "network"
"-P ALL" = "per_cpu"
-q = "queue"
-R = "mem"
-r = "mem_util"
-S = "swap_util"
-u = "cpu_util"
-v = "inode"
-W = "swap"
-w = "task"
# -H = "hugepages" # only available for newer linux distributions
# "-I ALL" = "interrupts" # requires INT activity
#
#
## Device tags can be used to add additional tags for devices. For example the configuration below
## adds a tag vg with value rootvg for all metrics with sda devices.
# [[inputs.sysstat.device_tags.sda]]
# vg = "rootvg"
```
### Measurements & Fields:
#### If group=true
- cpu
- pct_idle (float)
- pct_iowait (float)
- pct_nice (float)
- pct_steal (float)
- pct_system (float)
- pct_user (float)
- disk
- avgqu-sz (float)
- avgrq-sz (float)
- await (float)
- pct_util (float)
- rd_sec_pers (float)
- svctm (float)
- tps (float)
And much more, depending on the options you configure.
#### If group=false
- cpu_pct_idle
- value (float)
- cpu_pct_iowait
- value (float)
- cpu_pct_nice
- value (float)
- cpu_pct_steal
- value (float)
- cpu_pct_system
- value (float)
- cpu_pct_user
- value (float)
- disk_avgqu-sz
- value (float)
- disk_avgrq-sz
- value (float)
- disk_await
- value (float)
- disk_pct_util
- value (float)
- disk_rd_sec_per_s
- value (float)
- disk_svctm
- value (float)
- disk_tps
- value (float)
And much more, depending on the options you configure.
### Tags:
- All measurements have the following tags:
- device
And more if you define some `device_tags`.
### Example Output:
With the configuration below:
```toml
[[inputs.sysstat]]
sadc_path = "/usr/lib/sa/sadc" # required
activities = ["DISK", "SNMP", "INT"]
group = true
[inputs.sysstat.options]
-C = "cpu"
-B = "paging"
-b = "io"
-d = "disk" # requires DISK activity
-H = "hugepages"
"-I ALL" = "interrupts" # requires INT activity
"-n ALL" = "network"
"-P ALL" = "per_cpu"
-q = "queue"
-R = "mem"
"-r ALL" = "mem_util"
-S = "swap_util"
-u = "cpu_util"
-v = "inode"
-W = "swap"
-w = "task"
[[inputs.sysstat.device_tags.sda]]
vg = "rootvg"
```
you get the following output:
```
$ telegraf -config telegraf.conf -input-filter sysstat -test

If you change the group value to false like below:
```toml
[[inputs.sysstat]]
sadc_path = "/usr/lib/sa/sadc" # required
activities = ["DISK", "SNMP", "INT"]
group = false
[inputs.sysstat.options]
-C = "cpu"
-B = "paging"
-b = "io"
-d = "disk" # requires DISK activity
-H = "hugepages"
"-I ALL" = "interrupts" # requires INT activity
"-n ALL" = "network"
"-P ALL" = "per_cpu"
-q = "queue"
-R = "mem"
"-r ALL" = "mem_util"
-S = "swap_util"
-u = "cpu_util"
-v = "inode"
-W = "swap"
-w = "task"
[[inputs.sysstat.device_tags.sda]]
vg = "rootvg"
```
you get the following output:
```
