1. A system, comprising: a first interface configured to receive log data; a set of one or more processors; a memory coupled with the set of one or more processors, wherein the memory is configured to provide the set of one or more processors with instructions which when executed cause the set of one or more processors to: analyze the received log data at least in part by: clustering portions of the log data into clusters of similar data portions; and subsequent to the clustering, dynamically generating a signature for each cluster, wherein comparison of subsequent log data with the signature indicates whether the subsequent log data belongs in the cluster; and cause information associated with the analysis to be displayed to a user; a storage configured to store a plurality of signatures including the dynamically generated signature in a signature library, wherein the library is accessible by a first and second user, and wherein the first user can use the plurality of signatures in conjunction with data that is not accessible to the second user; and a second interface configured to receive user input associated with taking action with respect to the displayed information.
