I'd like to add a new API TSHttpTxnCacheStateGet() to be able to get more
insight into cache operations (e.g read_while_write, open read tries, open
write tries, cache volume used etc) on a given Txn.
Below's the proposal with the info I'd like the new API return along with the
API signature. I've opened TS-3881 to track this.
Please provide comments/suggestions.
+typedef enum {
+ TS_CACHE_TXN_STATE_HIT_RAM,
+ TS_CACHE_TXN_STATE_READ_WHILE_WRITER,
+ TS_CACHE_TXN_STATE_OPEN_READ_TRIES,
+ TS_CACHE_TXN_STATE_OPEN_WRITE_TRIES,
+ TS_CACHE_TXN_STATE_CACHE_VOLUME,
+ TS_CACHE_TXN_STATE_LAST_ENTRY
+} TSCacheTxnStateKey;
+
+/* Get Cache Lookup state, useful for understanding how a lookup was performed
*/
+/**
+ Return the particular cache lookup info requested.
+
+ @param txnp the transaction pointer
+ @param key the requested cache lookup info.
+ @param TSMgmtInt a pointer to a integer where we will store the metric value
+
+ @return @c TS_SUCCESS if the metric is supported, TS_ERROR otherwise
+
+*/
+tsapi TSReturnCode TSHttpTxnCacheStateGet(TSHttpTxn txnp, TSCacheStateKey key,
TSMgmtInt *value);
