@keyvhq/stats
Collects metrics for a Keyv instance over time.
Install
npm install --save @keyvhq/stats
Usage
Wrap your keyv instance with @keyvhq/stats
:
const KeyvStats = require('@keyvhq/stats')
const KeyvRedis = require('@keyvhq/redis')
const Keyv = require('@keyvhq/core')
const keyv = KeyvStats(new Keyv({ store: new KeyvRedis() }))
That adds some methods for getting stats over your keyv instance:
await keyv.get('foo')
keyv.stats.info()
// => {
// hit: { value: 0, percent: '0%' },
// miss: { value: 1, percent: '100%' },
// total: 1
// }
await keyv.set('foo', 'bar')
await keyv.get('foo')
await keyv.get('foo')
keyv.stats.info()
// => {
// hit: { value: 2, percent: '67%' },
// miss: { value: 1, percent: '33%' },
// total: 3
// }
keyv.stats.reset()
