Monitor totalSupply of cbETH (via Interval)
Here is an example to monitor total Supply of cbETH.
const blockHandler = async function(_:any, ctx: StakedTokenV1Context) {
const tokenInfo = await token.getERC20TokenInfo(ctx.contract.address)
const totalSupply = (await ctx.contract.totalSupply()).scaleDown(tokenInfo.decimal)
ctx.meter.Gauge("total_supply").record(totalSupply, {token: tokenInfo.symbol})
}
StakedTokenV1Processor.bind({address: CBETH_PROXY})
.onBlockInterval(blockHandler)
You could also write it using Time Interval instead of block
StakedTokenV1Processor.bind({address: CBETH_PROXY})
.onTimeInterval(blockHandler)
Here, you could see
- The
totalSupply
can be accessed by callingctx.contract.totalSupply()
- You can submit the metric
total_supply
typed Gauge by callingctx.meter.Gauge("total_supply").record(totalSupply, {token: tokenInfo.symbol})
