Monitoring Foyle With Honeycomb
How to monitor Foyle with Honeycomb
What You’ll Learn
- How to use Opentelemetry and Honeycomb To Monitor Foyle
Setup
Configure Foyle To Use Honeycomb
foyle config set telemetry.honeycomb.apiKeyFile = /path/to/apikey
Download Honeycomb CLI
- hccli is an unoffical CLI for Honeycomb.
- It is being developed to support using Honeycomb with Foyle.
TAG=$(curl -s https://api.github.com/repos/jlewi/hccli/releases/latest | jq -r '.tag_name')
# Remove the leading v because its not part of the binary name
TAGNOV=${TAG#v}
OS=$(uname -s | tr '[:upper:]' '[:lower:]')
ARCH=$(uname -m)
echo latest tag is $TAG
echo OS is $OS
echo Arch is $ARCH
LINK=https://github.com/jlewi/hccli/releases/download/${TAG}/hccli_${TAGNOV}_${OS}_${ARCH}
echo Downloading $LINK
wget $LINK -O /tmp/hccli
Move the hccli binary to a directory in your PATH.
chmod a+rx /tmp/hccli
sudo mv /tmp/hccli /tmp/hccli
On Darwin set the execute permission on the binary.
sudo xattr -d com.apple.quarantine /usr/local/bin/hccli
Configure Honeycomb
- In order for
hcclito generate links to the Honeycomb UI it needs to know base URL of your environment. - You can get this by looking at the URL in your browser when you are logged into Honeycomb.
- It is typically somethling like
https://ui.honeycomb.io/${TEAM}/environments/${ENVIRONMENT}
- You can set the base URL in your config
hccli config set baseURL=https://ui.honeycomb.io/${TEAM}/environments/${ENVIRONMENT}/
- You can check your configuration by running the get command
hccli config get
Measure Acceptance Rate
- To measure the utility of Foyle we can look at how often Foyle suggestions are accepted
- When a suggestion is accepted we send a LogEvent of type
ACCEPTED - This creates an OTEL trace with a span with name
LogEventand attributeeventType == ACCEPTED - We can use the query below to calculate the acceptance rate
QUERY='{
"calculations": [
{"op": "COUNT", "alias": "Event_Count"}
],
"filters": [
{"column": "name", "op": "=", "value": "LogEvent"},
{"column": "eventType", "op": "=", "value": "ACCEPTED"}
],
"time_range": 86400,
"order_by": [{"op": "COUNT", "order": "descending"}]
}'
hccli querytourl --dataset foyle --query "$QUERY" --open
Token Count Usage
- The cost of LLMs depends on the number of input and output tokens
- You can use the query below to look at token usage
QUERY='{
"calculations": [
{"op": "COUNT", "alias": "LLM_Calls_Per_Cell"},
{"op": "SUM", "column": "llm.input_tokens", "alias": "Input_Tokens_Per_Cell"},
{"op": "SUM", "column": "llm.output_tokens", "alias": "Output_Tokens_Per_Cell"}
],
"filters": [
{"column": "name", "op": "=", "value": "Complete"}
],
"breakdowns": ["trace.trace_id"],
"time_range": 86400,
"order_by": [{"op": "COUNT", "order": "descending"}]
}'
hccli querytourl --dataset foyle --query "$QUERY" --open
