| `fluentd.metadata.cacheRefresh` | Option to control the interval at which metadata cache is asynchronously refreshed (in seconds). | `3600` |
| `fluentd.metadata.cacheRefreshVariation` | Option to control the variation in seconds by which the cacheRefresh option is changed for each pod separately. For example, if cache refresh is 1 hour and variation is 15 minutes, then actual cache refresh interval will be a random value between 45 minutes and 1 hour 15 minutes, different for each pod. This helps spread the load on API server that the cache refresh induces. Setting this to 0 disables cache refresh variation. | `900` |

Setting this to a non-zero values ensures the traffic to api server is much distributed. | `0` |
