@keyvhq/stats

Collects metrics for a Keyv instance over time.

npm install --save @keyvhq/stats

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()

Type: object
Default: { hit: 0, miss: 0}

The data to set for first time or when .stats.reset() is called.

Type: number
Default: 1500

Type: string
Default: '__keyv_stats__'

The key used for storing the stats inside the store.

Returns the collected stats for the store in the shape:

{
  hit: {
    value: number
    percent: string
  },
  miss: {
    value: number
    percent: string
  }
  total: number
}

Resets the stats counters.

Peforms a save of the current buffered stats into the store.
